Arrange the following electromagnetic waves in the increasing order of their wavelength.

(A) X-rays
(B) Radio waves
(C) Gamma rays
(D) Microwaves

Choose the correct answer from the options given below:

(C), (A), (D), (B)

The correct answer is Option (2) → (C), (A), (D), (B)

Wavelength order: $\gamma$-rays < X-rays < Microwaves < Radio waves

So, increasing order of wavelength:

(C) Gamma rays < (A) X-rays < (D) Microwaves < (B) Radio waves

${C \; \lt \; A \; \lt \; D \; \lt \; B}$
