Detailed explanation-1: -The distance between crests is the wavelength.
Detailed explanation-2: -The crest is the highest point of the wave and the trough is the lowest point of the wave. Radio waves are long waves, and can measure thousands of yards long from crest to crest. Microwaves have wavelengths of only a few millimeters, and cosmic rays are only a tiny fraction of a millimeter in length.
Detailed explanation-3: -EXPLANATION: The distance between two crests is called the wavelength of the wave. Hence the correct answer is option 3.
Detailed explanation-4: -The separation between adjacent crests (or adjacent troughs) of a wave is equal to the wavelength. The separation between a crest and an adjacent trough is half the wavelength. If this distance is 10 cm, the wavelength would be 20 cm.
