Answer 1

radio waves, microwaves, infrared, visible, UV, X-rays, gamma rays

Step-by-step explanation:

Electromagnetic waves consist of oscillating electric and magnetic fields which vibrate in a direction perpendicular to the direction of motion of the wave (transverse wave). Electromagnetic waves travel in a vacuum with a speed of
`c=3.0\cdot 10^8 m/s` (speed of light), and they are classified into 7 different types according to their wavelength.

From longer to shorter wavelength, these types are:

Radio waves (wavelength > 30 cm)

Microwaves (30 cm -
`5 \mu m`)

Infrared (
`5 \mu - 750 nm`)

Visible light (750 nm - 380 nm)

UV radiation (380 nm - 8 nm)

X-rays (8 nm - 6 pm)

Gamam rays (< 6 pm)
