Question

Arrange the following radiation in the order of decreasing wavelength.

• A. Microwaves
• B. Gamma rays
• C. Infrared
• D. Visible light
• E. Ultraviolet

Answer 1

The correct option is
Wavelength range for different rays of the electromagnetic spectrum is as follows:
Gamma ($\gamma$) rays - less than $1\text{nm}$
Ultraviolet rays - $10\text{nm}-400\text{nm}$
Visible light - $400\text{nm}-800\text{nm}$
Infrared rays - $800\text{nm}-{10}^5\text{nm}$
Microwaves - ${10}^5\text{nm}-{10}^8\text{nm}$

The electromagnetic spectrum arranged according to decreasing wavelengths:
Microwaves > Infrared > Visible light > UV rays > Gamma rays
