Question

1. if the wavelength of an infrared wave gets longer, which type of electromagnetic radiation could it become?

a. x - ray
b. microwave
c. visible

Explanation:

In the electromagnetic spectrum, as wavelength increases, we move towards waves with longer - wavelength types. Infrared waves have wavelengths between microwaves and visible light. When the wavelength of an infrared wave gets longer, it moves towards the microwave region since microwaves have longer wavelengths than infrared. X - rays have much shorter wavelengths than infrared.

Answer:

b. Microwave
