Which type of electromagnetic radiation has a greater wavelength than red light?
Correct answer: A. Infrared
- A. Infrared
- B. X-rays
- C. UV
- D. Gamma rays
Explanation
The electromagnetic spectrum consists of various types of radiation, each with a different wavelength. The wavelength of electromagnetic radiation increases in the following order:Gamma rays < X-rays < Ultraviolet (UV) < Visible light (including red light) < InfraredTherefore, among the options provided, infrared radiation has a greater wavelength than red light.

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
