Answer:
Microwaves and radio waves
Explanation:
The electromagnetic spectrum is the classification of the electromagnetic waves according to their wavelength.
From shortest to longest wavelength, they are classified as follows:
Gamma rays < 6 pm
X-rays 6 pm - 10 nm
Ultraviolet 10 nm - 380 nm
Visible light 380 nm - 750 nm
Infrared radiation [tex]750 nm - 5 \mu m[/tex]
Microwaves [tex]5 \mu m -0.3 m[/tex]
Radio waves > 0.3 m
From the list, we see that infrared rays have shorter wavelength than microwaves and radiowaves.
