Detailed explanation-1: -Electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible spectrum, ultraviolet waves, X-rays and gamma rays. It does not include alpha rays.

Detailed explanation-2: -Examples of EM radiation include radio waves and microwaves, as well as infrared, ultraviolet, gamma, and x-rays. Some sources of EM radiation include sources in the cosmos (e.g., the sun and stars), radioactive elements, and manufactured devices.

Detailed explanation-3: -Electromagnetic waves are generally depicted as sine waves. Sine waves (actually their generalization as complex exponentials, but it comes down to the same thing) are one of the solutions of the differential equation we get from Maxwell’s equations which describe classical electromagnetism.

Detailed explanation-4: -Electromagnetic waves do not show interference and diffraction.
