Which of the following is true for the transition of electrons from a higher energy to a lower energy state?

Question

Choose one answer.
a. The greater the energy difference between the levels, the more is the wavelength of the photons emitted.
b. The greater the energy difference between the levels, the less is the wavelength of the photons emitted.
c. The greater the energy difference between the levels, the less is the frequency of the photons emitted.
d. The energy difference is not related to frequency or wavelength of the photons emitted.

Answer 1

change in energy = h f
where f is the frequency of the photon emitted and h is Planck constant.

T c = (1/f)c = wavelength
so f = c/wavelength
so
change in energy = hc/wavelength
so
big change in energy goes with small wavelength

That is all I will do without seeing your analysis and what your answers would be.
