Which of the following statements is true? A. X-rays have longer wavelengths than microwaves. B. Radio waves have shorter wavelengths that X-rays. C. Gamma rays have longer wavelengths that UV rays. D. Gamma rays have shorter wavelengths than microwaves.

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The wavelength is the distance between peaks in the wave, or the distance from crest to crest. If a wave is passing by a point, the frequency is the time interval between passing peaks. Therefore as the wavelength increases, the frequency decreases (and vice-versa).

X-rays have longer wavelengths than gamma rays. The wavelengths of X-rays are shorter than the wavelengths of ultraviolet waves, radio waves, and infrared waves.

The X-rays have longer wavelengths than the microwaves. Hence, the statement (A) is correct.

The given problem is based on the concept of electromagnetic waves and electromagnetic spectrum.

The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The wavelength is the distance between peaks in the wave, or the distance from crest to crest. If a wave is passing by a point, the frequency is the time interval between passing peaks. Therefore as the wavelength increases, the frequency decreases (and vice-versa).

X-rays have longer wavelengths than gamma rays and microwaves. The wavelengths of X-rays are shorter than the wavelengths of ultraviolet waves, radio waves, and infrared waves.

Thus, we can conclude that the X-rays have longer wavelengths than the microwaves. Hence, the statement (A) is correct.
