Question

Arrange the following radiation in increasing order of their wavelength:
(A) UV-C
(B) UV-B
(C) UV-A
(D) Infra-red
(E) Microwave
Choose the correct answer from the options given below:

• A. (C), (B), (A), (D), (E)
• B. (A), (B), (C), (E), (D)
• C. (A), (B), (C), (D), (E)
• D. (E), (D), (C), (B), (A)

Answer 1

The Correct Option is C

The wavelength ranges for electromagnetic radiation are typically:

• UV-C: 100–280 nm
• UV-B: 280–315 nm
• UV-A: 315–400 nm
• Infra-red: 700 nm to 1 mm
• Microwave: 1 mm to 1 meter

Ordered by increasing wavelength, these are: (A) UV-C, (B) UV-B, (C) UV-A, (D) Infra-red, (E) Microwave.

The correct sequence is: (A), (B), (C), (D), (E).
