Question 0

2. Electromagnetic spectrum

Answer 0

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

Question 1

1. Electromagnetic wave

Answer 1

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

Question 2

3. Radio waves

Answer 2

Electromagnetic waves with the longest wavelength and lowest frequencies

Question 3

Microwaves

Answer 3

Short 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 wavelength shorter than microwaves. Carry more energy than micro waves often called heat waves

Question 6

Thermogram

Answer 6

An image that shows regions of different temperatures in different colors

Question 7

Visible light

Answer 7

Electromagnetic waves you can see

Question 8

Ultraviolet rays

Answer 8

Electromagnetic waves with a shorter frequency that you can see, carries more energy than visible light and can kill living cells

Question 9

X-rays

Answer 9

Electromagnetic waves with a shorter Wave length then ultraviolet rays and carry more energy than ultra violent and can penetrate most matter

Question 10

Gamma rays

Answer 10

Shortest wavelength, and fastest frequency
