Question

Among ultraviolet rays, X-rays, gamma rays and microwaves, which have the shortest wavelength?

G1 Physics · Accepted Answer

Step 1: Wavelength generally increases in the order gamma rays < X-rays < ultraviolet < visible < infrared < microwaves. Step 2: Of the offered UV rays, X-rays, gamma rays and microwaves, gamma rays have the highest typical frequency. Step 3: Therefore gamma rays have the shortest wavelength: C. Final answer: (C) y-rays.
