Which type of wave has the longest wavelength in the electromagnetic spectrum?

Radio waves
Infrared light
Visible light
Ultraviolet light

The correct answer is: Radio waves

Radio waves have the longest wavelength in the electromagnetic spectrum as they have the lowest frequency and energy. Infrared light, visible light, and ultraviolet light all have shorter wavelengths and higher frequencies and energies, respectively. This means that compared to radio waves, these three types of waves have more energy and can be used for different purposes such as in communication, heat sensing, and vision. Therefore, radio waves are the only correct answer as they have the longest wavelength in the electromagnetic spectrum.
