5.What is the shortest-wavelength X-ray photon emitted in an X-ray tube subject to 50 kV?

A. 0.025 nm

- 0.25 nm
- 2.5 nm
- 25 nm
- none of the given answers

Answer #1

1)b) 5eV photon has shorter wavelength as the photon has higher frequency and velocity of photons is constant (velocity of light).

2)a) energy of the particle is inversely proportional to the square of the dimension of box, so for the smaller box the energy of the particle in ground state will be greater.

3) a) Schrodinger wave equation governs quantum mechanics system.

4) a) wavelength of peak intensity decreases as temperature increases (wein displacement law)

5) a) E=h*c/wavelength

wavelength =h*c/E

w=(6.626*3*10^-26)/(1.6*50000*10^-19)

w=2.484*10^-11 m

w=0.02484 nm

w=0.025nm
