Answer 2

Seems a bit of a strange question to me - the ratio of the photon energies of photons of different frequency is just the ratio of their frequencies.
I'm not quite sure what is meant by 'average gamma ray', since there is really no upper limit on that range.
The conversion from wavelength to frequency is given by \[f=c/\lambda\]
if f is the frequency in Hz, c the speed of light (meters per second) and lambda the wavelength in meters.
Ultraviolet wavelengths are in the 10 to 400 nanometer range, so 200 x 10^-9 m would be somewhere in the midrange.
A 1Mev gamma ray would have a frequency of about 2.5 x 10^20 Hz.

Answer 3

thankyo u so much @ProfBrainstorm i had no idea how to explain this at all.
