Electromagnetic Waves

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 waves, visible light, ultraviolet rays, x-rays, and gamma rays.

Question 1

Electromagnetic Wave

Answer 1

A transverse wave that is made up of vibrating electric and magnetic fields that move through space or some medium at the speed of light.

Question 2

Radio Waves

Answer 2

Electromagnetic waves with the longest wavelengths and the lowest frequencies.

Question 3

Microwaves

Answer 3

Electromagnetic waves that have a shorter wavelength 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 radiation that can be seen with the unaided eye.

Question 8

Ultraviolet Waves

Answer 8

Electromagnetic waves with wavelengths shorter than visible light, but longer than x-rays. Carry more energy than visible light and can damage or kill living cells.

Question 9

Gamma Rays

Answer 9

Electromagnetic waves with the shortest wavelengths and highest frequencies. Carry more energy than ultraviolet rays and can penetrate most matter.

Question 10

X-rays

Answer 10

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