Question

Quizplus · Accepted Answer

Gamma rays from a star produce the highest energy photons. They have very short wavelengths and high frequencies, which correspond to high energy photons. X-rays from a doctor's source and microwave ovens also produce high energy photons, but not as high as gamma rays. Heat lamps in a restaurant and radio waves from a local station produce much lower energy photons.
