Light of wavelength of 102.6 nm is emitted by a hydrogen atom. What are: a) Principal quantum number of lower (final) orbit b) Principal quantum number of higher (initial) orbit Of transition producing this emission? c) If electron angular quantum number of initial state is s what is orbital quantum number in final state?

What is the energy of a photon that has the same wavelength as a 100-eV electron? please provide given, reasoning, steps.

checking answer The spectrum of another astronomical object has a peak wavelength of 51 nanometers. What is the likely surface temperature of this object? Make that calculation, showing your work

Suppose that at a given time a quanton has the (unrealistic) wavefunction shown. If we per- form an experiment to locate the quanton at that time, what is the probalitiy that the result will be greater than zero? Explain your reasoning. (Assume that y(x) = 0 everywhere out- side the region shown. The size of the vertical and horizontal scales in not relevant.) *(x)

Calcium has a work function of 2.87eV. Which equation would you use to find the cutoff wavelength for the Calcium? Show your work in calculating the cutoff wavelength of calcium. What is the cutoff wavelength of Calcium? Which equation would you use to determine the frequency that corresponds to the wavelength? Show your work in calculating the frequency. What is the frequency that corresponds to the cutoff wavelength?

graphically to the right (note that the curve is a stralgl wwww 3 A quantum harmonic oscillator consists of a 100-gram mass attached to a spring with spring constant 60 N/m. This system, while ocillating, lowers its energy by dropping down one quantum state (quantum number n decreases by 1). If the energy that the oscillator loses is carried off by a photon, what would be the wavelength of this photon? Give your answer in meters. The answer does not depend on the oscillator's initial quantum state. A br ear vni
