Which one of the following lists is a correct representation of electromagnetic waves from longer wavelength to shorter wavelength? answerradio waves, uv, x-rays, microwaves, infrared, visible, gamma raysradio waves, microwaves, visible, x-rays, infrared, uv, gamma raysradio waves, infrared, microwaves, uv, visible, x-rays, gamma raysradio waves, microwaves, infrared, visible, uv, x-rays, gamma raysradio waves, infrared, x-rays, microwaves, uv, visible, gamma rays

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

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 (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 - )

Infrared ()

Visible light (750 nm - 380 nm)

UV radiation (380 nm - 8 nm)

X-rays (8 nm - 6 pm)

Gamam rays (< 6 pm)

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
