Question

Arrange gamma rays, ultraviolet radiation, infrared radiation and microwaves in decreasing wavelength.

G1 Physics · Accepted Answer

Step 1: Recall the inverse relationship between wavelength and frequency (c = fλ) for electromagnetic radiation in vacuum. Step 2: Microwaves have the longest wavelength of these four, followed by infrared, ultraviolet and gamma radiation. Step 3: Thus decreasing wavelength is microwave > infrared > ultraviolet > gamma. Answer D. Final answer: (D) microwaves, infrared, ultraviolet, gamma rays.
