Question

Suppose that 300 keV X-ray photons are aimed at a zinc cube (Zinc, Z = 30). According to the chart below, what effect will predominate when the X-rays hit the metal?

a) Photoelectric Effect 3
b) Compton Effect 3
c) Pair Production

Answer 1

the answer is option A = photoelectric effect

Step-by-step explanation:

If the threshold frequency of a metal is lower than the energy of X-rays, then photoelectric effect will happen.
