The waves emitted when a metal target is bombarded with high energy electrons are (a) Infrared rays (b) Radio Waves (c) Microwaves (d) X-rays

Answer: (d). High-energy electrons hitting a metal target decelerate and knock out inner-shell electrons. Both processes emit high-energy photons of very short wavelength, i.e. X-rays (the working of a Coolidge tube). So the answer is (d) X-rays.
