Ch3 Elctromagnetic Waves Vocac for Science

Question 0

electromagnetic spectrum

Answer 0

the complete range of electromagnetic waves placed in order of increasing frequency. Is made up of radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays.

Question 1

Electromagnetic wave

Answer 1

A transverse wave that involves the transfer of electric and magnetic energy. A transverse wave that is made up of vibrating electric and magnetic field that move through space or the medium at the speed of light.

Question 2

radio waves

Answer 2

electromagnetic waves with the longest wavelengths and

lowest frequencies.

Question 3

microwaves:

Answer 3

electromagnetic waves that have shorter wavelengths

and higher frequencies than radio waves.

Question 4

radar:

Answer 4

a system that uses reflected radio waves to detect objects and
measure their distance and speed.

Question 5

infrared rays

Answer 5

electromagnetic waves with shorter wavelengths and
higher frequencies than microwaves. Carry more energy than
microwaves, and are often called heat rays.

Question 6

thermogram:

Answer 6

an image that shows regions of different temperatures in

different colors.

Question 7

visible light

Answer 7

electromagnetic waves that you can see.

Question 8

ultraviolet rays

Answer 8

electromagnetic waves with shorter wavelengths and higher frequencies than those of visible light. Carry more energy than visible light and can damage or kill living cells

Question 9

X-rays

Answer 9

electromagnetic waves with shorter wavelengths and higher frequencies than ultraviolet rays. Carry more energy than ultraviolet rays and can penetrate most matter.

Question 10

gamma rays

Answer 10

electromagnetic waves with the shortest wavelengths and highest frequencies. Have the greatest amount of energy and are the most penetrating.
