If a beam of X-rays is scattered from protons instead of electrons, the change in the wavelength of this X-ray beam for a given angle of scattering decreases.
Indicate whether the statement is true or false
Question 2
A ray of light, which is traveling in a vacuum, is incident on a glass plate (n = ng). For increasing angles of incidence, the angle of refraction

B) decreases, approaching the limiting value of zero degrees.
C) increases, approaching the limiting value of sin-1 (1/ng) degrees.
D) increases, approaching the limiting value of sin-1 (ng) degrees.
