Answer:
Relatively small part of the electromagnetic spectrum
Step-by-step explanation:
Let us take a look at the electromagnetic spectrum
Radio waves
Wavelength =

Microwaves
Wavelength =

Infrared waves
Wavelength =

Visible waves
Wavelength =

Radio waves
Wavelength =

Ultraviolet waves
Wavelength =

X ray waves
Wavelength =

Gamma ray waves
Wavelength =

So, it can be seen that the visible light makes up a relatively small part of the electromagnetic spectrum.
