Which listed electromagnetic radiation has the smallest wavelength?

Question

G1 Physics · Accepted Answer

Step 1: In the spectrum, gamma radiation has higher frequency than X-rays, ultraviolet radiation and microwaves. Step 2: Since every EM wave obeys c = fλ, a larger frequency means a smaller wavelength. Step 3: Among the given choices gamma rays have the smallest wavelength. B. Final answer: (B) Gamma rays.
