The energy of a photon is E = hf = hc/λ and the momentum of the photon is p = hf/c = h/λ = E/c. The relativistically correct expression for the energy of the electron is E e = (p e 2 c 2 + m e 2 c 4) 1/2. The initial momentum of the electron is (nearly) zero. Energy conservation requires E i + E ei = E f + E ef, or E i + m e c 2 = E f + (p ef ... E = hc / λ Just make sure that the units for c and λ are the same. Problem #2: If it takes 3.36 x 10 -19 J of energy to eject an electron from the surface of a certain metal, calculate the longest possible wavelength, in nanometers, of light that can ionize the metal. E = mc2 • For a photon with energy E = hν= hc/λ: E = mc2 = hc/λ⇒ mc= h/λ⇒ λ= h/mc ⇒λ= h/p p – photon momentum – The equation shows that the wave-like photons have particle-like mass and momentum • Experimental evidence (Compton, 1923) • De Broglie’s hypothesis(1924) – all matter has wave-like properties (just as waves have ET = E 1 + E 2 ….. (1) Where E 1 is Energy of first emitted photon emitted and E 2 is Energy of second emitted photon. Energy E and wavelength λ of a photon are related by the equation E= (hc)/ (λ)….. (2) Where Plancks constant = h, c is velocity of light. Substituting the values from (2) in (1) we get (hc/λ T) = (hc)/ (λ 1) + (hc)/ (λ 2) (1) E light = hν light = hc/λ light = ΔE = E UO – E OO Before the absorption of a photon, the electrons within the compound are in the lowest energy orbitals possible. Such an electron configuration is called the ground state. When a photon of visible radiation is absorbed by a compound an electron is promoted from an occupied orbital to Φ = h휈 th = hc/λ th. Relationship between the Frequency of the Incident Photon and the Kinetic Energy of the Emitted Photoelectron. Therefore, the relationship between the energy of the photon and the kinetic energy of the emitted photoelectron can be written as follows. E photon = Φ + E electron ⇒ h휈 = h휈 th + ½m e v 2. Where, Jsc =qb∫ s(E)QE(E)dE Where bs (E) is the incident spectral photon flux density, the number of photons of energy in the range E to E+dE which are incident on unit area in unit time and q is the electronic charge. QEdepends on the solar cell material and electronic characteristics, but does not depend on the incident spectrum. E = hc λ = 1240 λ Q.1.

The emission spectrum consists of discrete lines corresponding to the differences in energy levels characteristic of, and unique to, the atoms of the element. The lines are normally The energy E of a photon is equal to hv = hc/λ, where v is the frequency of the electromagnetic radiation and λ is its wavelength. Energies in quantum physics are commonly expressed in electron volts (1 eV = 1.6 × 10 −9 J) ... is the sum of a number of terms of the form:

2021.12.03 03:23 bigstepperz Question from a new person!
Okay, I'm an absolute newbie with redstone, so I don't know if this is even possible (or inversely, is hilariously easy and I'm just not clicking), but this is my dilemma.
I am in a survival multiplayer world with a few friends, and I have a base in the sky, based off the Kingdom of Zeal from Chrono Trigger. From ground level to the earliest possible entry point, it's 36 blocks in the air.
In Chrono Trigger, they have teleportation pads that take you from ground level to the castles in the sky. I was wondering if there were any way to send myself up in the air the 36 blocks required *without* some sort of water pillaflying machine.

One of our main priorities is making our token safe, fair and completely transparent for all investors. Thats why we have renounced ownership of the Shiba Max contract on launch ensuring no individual or entity has control of Shiba Max, ensuring that it is decentralized and secure for all investors.
Our Tokenomics are as follows:
Auto-Liquidity Generation: 7% of all Shiba Max transactions will be contributed to building Liquidity ensuring the growth, stability, and sustainability of the token. This feature ensures that the price of the token is backed by a constantly growing liquidity pool. Multiple secure liquidity pools will be added as we grow, and our token is listed on centralized exchanges such as Bilaxy and Hotbit. The rate of contributions will only increase as our community grows and trading volume increases providing stability and security to our investors.
Decentralization: Contract Ownership was renounced at launch as a result of this action no individual or entity has ownership of the contract, making Shiba Max secure and fair for our community and truly decentralized. 100% of Liquidity was locked on launch (Please refer to our FAQ section for link) to ensure security and peace of mind for our investors.Shiba Max was tested extensively using the testnet prior to launch to ensure absolute security and accuracy of function, it was designed to be scalable, self-sustaining, and to scale seamlessly and frictionlessly on a fully autonomous and rapidly growing DeFi ecosystem.
Shiba Maximum Rewards: All holders will have their Shiba Max balance grow through RFI Rewards at intervals as the Shiba Max Army grows. This function will allow the Army to effectively earn interest rewards which will increase as our community grows. Our mission is to ensure that the Shiba Max Army is rewarded as our domination of the Crypto Market continues on.
The Shiba Max NFT Marketplace and its offerings is brimming on the horizon. We will be working garner a roster of the best Digital artists, Influencers, Celebrities, and Athletes to have an all-star lineup of NFT releases at launch. The Dynamic NFT releases would also be paired with Physical Merchandise to add further value to our Marketplace offerings. Airdrops will also be going out to our top shillers and holders.

I often find myself narrating fantasies to myself. Usually involving meeting someone fictitious, going to a fictional world (like being a human psychic in Steven Universe) or an asanine success strategy that doesn't work. (Like making a full game in just 8 months, getting enough Kickstart money AFTER the game is already complete, etc.)
The problem lies in 3 things.

2021.12.03 03:23 AeroEngineer90 [Landlord AZ] Dishwasher Suggestions
I have TERRIBLE luck with appliances. Every appliance I've bought for my house has broken within 5 years and needed to be replaced. My newest appliance to bite the dust is the dishwasher. What dishwashers have you guys been buying that seem to last or you expect to last? I'd like it to last at least 10 years or is that wishful thinking. The property is in the Phoenix Arizona area if that makes a difference. Thanks in advance.

2021.12.03 03:23 thesincorner Woo hoo!
So, I started writing this one fic like… 6 months ago or so off and on, and made a second fic I write along side it like 4 1/2 months ago, and apparently people like them a lot!
Like, I wrote them to fulfill my want for a fic as I had not seen this or that done and wanted to give a crack at them, and then they kinda blew up during one of my mini breaks because of work and stuff. And so here I am really excited to write some more for them, and also nearly at the point of strangling the people that say the fact I skimmed over this one area, for brevity sake as the chap was the longest yet, and they seem to think it completely ruined the chap.
Good news tho, 99% of the comments after word said the opposite and they loved it. I guess I really was not prepared for my fics to ever be found ya know? Much less having people who don’t know my plans for the story thinking I made a mistake in how I paced and payed the ground work for PLOT was wrong. It kind grinds my gears very tightly.
Okay, thanks for reading my rant if you did, ~^

2021.12.03 03:23 NateWagnerOfWhiterun To all the people who have the InterestingNPCs mod, have you ever came across a character from the mod who you thought was in the base game?
I ran into this guy named Nitter at the Solitude lighthouse, and his voice acting was amazing and his story was very interesting and believable. I was super surprised to figure out he was apart of a mod. Anyone else have any stories similar to this?
