Which Electromagnetic Radiation Has the Greatest Photon Energy?

[vicks]

1. Compton scattering from electrons is most easily observed for:

*microwaves *infrared light *visible light *ultraviolet light *x rays

I Think it refer to x ray . but not sure what do you think guyz .. please tell me if you can

2.Which of the following electromagnetic radiations has photons with the greatest energy?

*blue light * microwave * x ray * radio wave * yellow light

as far as i think its radio wave what do you say about this .. THank you

Well how have you reasoned?

For the first, Q do you have a formula for the change in wavelength/frequency for scattered photons?

For the second Q, what is the relation between photon energy and wavelength of the EM-wave? How would you order the alternatives you've got with respect to increasing wave lenght?

(I will not just give you the answers, I want you also to be able to see WHY they are the right answers, that is the purpose of physics forum)
