100

Which type of electromagnetic wave is between Ultraviolet rays and Infrared rays?

Visible light

100

A transverse wave that involves the transfer of electric and magnetic energy

Electromagnetic wave

100

Complete range of electromagnetic waves placed in order from highest amount of energy to least amount of energy.

Electromagnetic spectrum

100
An image that shows regions of different temperatures in different colors.

Thermogram

100

AM stands for . . . 

Amplitude Modulation

200

Which electromagnetic wave has the lowest energy level?

Radio waves

200

The energy that electromagnetic waves transfer through

Electromagnetic radiation

200

Used in broadcasting to carry signals for radio programs. Longest wavelengths and lowest frequency on the spectrum.

Radio waves

200

Electromagnetic waves that you can see. Make up only a small portion of the spectrum. Shorter wavelengths and higher frequencies than infrared rays.

Visible lights

200

FM stands for . . .

Frequency Modulation

300

Which electromagnetic wave has the highest energy level?

Gamma Rays

300

Light that passes a polarized filter

Polarized light

300

Shorter wavelengths and higher frequencies than radio waves.

Microwaves

300

Energy can damage or kill living cells. Electromagnetic waves just shorter than those of visible light. Higher frequencies than visible light, so they carry more energy.

Ultraviolet rays

300
Method of broadcasting signals by changing the frequency of a wave

Frequency Modulation

400

What is the order of the spectrum from lowest to highest energy?

Radio waves, Radar, Microwaves, Infrared rays, Visible light, Ultraviolet rays, X-rays, Gamma rays

400

A packet of light energy

Photon

400

A system that uses reflected microwaves to detect objects and measure their distance and speed.

Radar

(RAdio Detection And Ranging)

400

Can penetrate most matter, can't pass through bones or teeth. X-rays carry more energy than ultraviolet rays. Wavelengths just shorter than those of ultraviolet rays. Frequencies just a little higher than ultraviolet rays.

X-rays

400

Method of broadcasting signals by changing the amplitude of a wave

Amplitude Modulation

500

What is the order of the spectrum from highest to lowest energy?

Gamma rays, X-rays, Ultraviolet rays, Visible light, Infrared rays, Microwaves, Radar, Radio waves

500

Stream of tiny photons that can knock electrons out of place

Photoelectric effect

500

Electromagnetic waves with wavelengths shorter than those of microwaves. Often called heat rays.

Infrared rays

500

Most penetrating wave on the spectrum. Shortest wavelengths and highest frequencies on spectrum.

Gamma rays

500

What is the difference between AM and FM?

AM is changing the amplitude while FM is changing the frequency.
