Question

Consider the following types of electromagnetic radiation:
(P) Radio waves
(Q) Visible light
(R) Gamma rays
(S) X-rays
Arrange these radiations in the increasing order of their wavelength. Choose the correct sequence from the options given below:

Professor PC Thomas Classes · Answer

Gamma rays (shortest wavelength)
X-rays
Ultraviolet
Visible light
Infrared
Microwaves
Radio waves (longest wavelength)
Given the radiations:
(P) Radio waves
[Q] Visible light
[R] Gamma rays
(S) X-rays
Arranging them in increasing order of their wavelength:
1. Gamma rays ( $R$ ) have the shortest wavelength.
2. $X$-rays $(S)$ have a longer wavelength than gamma rays.
3. Visible light $[Q]$ has a longer wavelength than $X$-rays.
4. Radio waves (P) have the longest wavelength among the given options.
Therefore, the increasing order of wavelength is: $\lambda_R<\lambda_S<\lambda_Q<\lambda_P$.
