Question

if the wavelength of an infrared wave gets longer, which type of electromagnetic radiation could it become?
electromagnetic spectrum
radio microwave infrared visible ultraviolet x - ray gamma ray
microwave
gamma
visible
x - ray

Explanation:

In the electromagnetic spectrum, as wavelength increases, we move from higher - energy, shorter - wavelength radiation to lower - energy, longer - wavelength radiation. Infrared has a longer wavelength than visible, ultraviolet, X - ray, and gamma ray. Among the options, radio and microwave have longer wavelengths than infrared. Since radio waves have the longest wavelengths in the electromagnetic spectrum among common types, and microwave is next in terms of longer wavelengths compared to infrared. When the wavelength of an infrared wave gets longer, it could become a microwave.

Answer:

Microwave
