Please show all the steps thank you very much
6. The one-dimensional wave function for a particle over all space... may be expressed as: 4, = Ae i(kx-ot) a) Apply the momentum and energy operators to ψ ( ie, pyr & EY) as to verify the following: pzhk and Eshω b) Substitute w into Schrödinger's equation...2m -2mārī = Ey as to verity the following: 2m ax
Only asking for accuracy. I'll make sure to leave a like :)
1. According to Planck's hypothesis, a. the energy of an incandescent body is quantized. b. the variable n can have any real number value. c. the frequency of vibration is inversely proportional to the energy. d. atoms constantly radiate electromagnetic waves when they vibrate. 6. Which of the following best describes the nature of light? a. Light has wave properties only. b. Light has particle properties only. c....
please do the full working everyone is just jumping to the
answer im trying to understand the working please
Light consists of photons: noninteracting quantum oscillator particles with an energy E-hv- e, where is their frequency, A is their wavelength, and c is their speed (ie the speed of light) The momentum of a photon, p has a special definition, because photons have no mass. We instead use the De Broglie identity p-. This means that we can relate the...

Show that if an electron is accelerated through V volts then the deBroglie wave- length in angstroms is given by λ-(1 ) 12 A thermal neutron has a speed v at temperature T 300 K and kinetic energy L. Calculate its deBroglie wavelength. State whether a beam of these neutrons could be diffracted by a crystal, and why? (b) Use Heisenberg's Uncertainty principle to estimate the kinetic energy (in MeV) of a nucleon...

Please can you show me how to do this part of the question. I
nearly got it, but I’m not sure where the 8*pi factor comes from at
the front. The energy is epsilon = c*p, which may be difficult to
read.
Then please can you go on to show the following via finding the
helmholtz free energy. I nearly got it, except for the 4 at the
front.
Thanks!

Please answer question i
thank you!
h) (4 pts) Ebonite, from which bowling balls are made is one of the most triboelectrically active substances. The precise mechanism for the triboclectric effect is still very much a scientific mystery. The surface of bonite will quickly pickup excess electrons as it moves through air. Moving charges comprise an electric current Oscillating electric currents generate radio waves. If the muss used in this question is ebonite, its oscillations will generate radio waves that...
2. A system consists of N very weakly interacting particles at a temperature T high enough that classical statistical mechanics is applicable. Each particle is fixed in space, has mass m, a. Calculate the heat capacity of this system of particles at this temperature in each of the i. The effective restoring force has magnitude κ x, where x is the displacement from and is free to perform one-dimensional oscillations about its equilibrium position. following cases: equilibrium. The effective restoring...
Question 8 please
5. We start with Schrodinger's Equation in 2(x,t) = H¥(x,t). We can write the time derivative as 2.4(x, t) = V(x,+) - (xt), where At is a sufficiently small increment of time. Plug the algebraic form of the derivative into Schrodinger's Eq. and solve for '(x,t+At). b. Put your answer in the form (x,t+At) = T '(x,t). c. What physically does the operator T do to the function '(x,t)? d. Deduce an expression for '(x,t+24t), in terms...
Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: λ=h/p, where λ is the wavelength, p the momentum, and h Planck's constant. Part...
1) (35 points) The wave function for a particle moving along x axis between the limits 0 and L is: (x)-C sin (nx xL) where n are 1, 2, 3, A) Determine the normalization constant C B) Why can't n take the value of 0, briefly explain C) For n-3 determine the values of x (in terms of L) that correspond to a maximum or a minimum in the wave function D) For n-3 determine the values of x (in...
