What type of electromagnetic radiation has the highest energy?

Radio waves
Ultraviolet
Visible light
Infrared

The correct answer is: Ultraviolet

Ultraviolet radiation has the highest energy out of the options given because it has a shorter wavelength and higher frequency compared to radio waves, visible light, and infrared. While potentially harmful in large doses, ultraviolet radiation has many practical uses such as in medical and cosmetic treatments. Radio waves, on the other hand, have the longest wavelength and lowest frequency and are often used for communication purposes. Visible light, although essential for our daily lives, has a moderate energy level compared to other forms of electromagnetic radiation. Infrared radiation has a longer wavelength and lower frequency than visible light and is often used for heating and thermal imaging. Therefore, out of the four options given, ultraviolet radiation has the highest energy.
