Which electromagnetic wave has the shortest wavelength?

Answer:

• Gamma rays have the lowest wavelength. 

• The electromagnetic spectrum consists of the following waves: Radio waves, Microwaves, Infrared waves, Visible light, UV rays, X-rays, and Gamma rays. The above listing of EM waves is done by taking increasing frequency or decreasing wavelength as a basis. 
• Among the above, radio waves have the minor frequency and longest wavelength, and gamma rays have the lowest and highest frequency. Since energy is directly proportional to frequency, we could say that Gamma rays have the highest energy in the above list.
• Therefore, we found the wavelength of Gamma rays to be less than 0.001 nm, so fortunately, the harmful gamma rays from space don’t cross the earth’s atmosphere.
