GENERAL KNOWLEDGE

Detailed explanation-1: -Gamma Rays have the smallest wavelength and the most energy of the waves in the electromagnetic spectrum.

Detailed explanation-2: -Japan-based researchers have developed an atomic X-ray laser that operates at 0.15 nm, the shortest wavelength ever, for an atomic laser, by nearly two orders of magnitude.

Detailed explanation-3: -Which means that the answer to our question is that gamma rays have a shorter wavelength than X-rays.

Detailed explanation-4: -Radio waves and microwaves lie at the longer end of the spectrum of electromagnetic energy (kilometers and meters to centimeters and milimeters), while x rays and gamma rays have very short wavelengths (billionths or trillionths of a meter).
