Question

Electromagnetic spectrum consists of

• A. Alpha radiation
• B. Gamma radiation
• C. Beta radiation
• D. All of these

Answer 1

The correct option is D All of these

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum. The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency.
