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:
Answer & explanation
Correct answer: option 2
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
${C \; \lt \; A \; \lt \; D \; \lt \; B}$
