Physics question (multiple choice)
when the number of electrons striking the anode of an x-ray tube increases, the of the emitted x-rays increases.
a) number
b) frequency
c) energy
d) wavelength

A) number

Explanation:

As we know that in production of X rays when high energy electrons collide with the anode then in each collision the kinetic energy of electron will release its kinetic energy in form of photons.

So here if more number of electrons collide with anode then more number of photons will release.

So here since number of photons are more due to increase number of collision so we will have more intensity of X rays

So here correct answer will be

A) number

less than one you can't create energy
