Mod 5 Lesson 1

Question 1

Electromagnetic radiation:

Answer 1

Electromagnetic radiation: energy that travels in waves from a single source and includes all of the types of energy on the electromagnetic spectrum

Question 2

Electromagnetic spectrum:

Answer 2

Electromagnetic spectrum: the collection of all known frequencies and wavelengths of electromagnetic radiation

Question 3

Frequency

Answer 3

Frequency: the number of waves that pass a given point in a given amount of time, usually one second

Question 4

Radiation

Answer 4

Radiation: method of heat transfer in which waves travel outward from a central source

Question 5

Visible light

Answer 5

Visible light: a form of electromagnetic radiation that is visible to the human eye and is made up of all of the colors of the rainbow

Question 6

Wavelength:

Answer 6

Wavelength: the distance from one point on a wave to the same point on the next wave

Question 7

The longer the wavelength, the lower the total energy of the wave.

True or False?

Answer 7

True

Question 8

The faster the frequency, the lower the total amount of energy of the wave.

True or False?

Answer 8

False

Question 9

Shorter Wavelength + Higher Frequency = Higher Energy

True or False?

Answer 9

True

Question 10

Longer Wavelength + Lower Frequency = _____ Energy

Lower or higher?

Answer 10

Lower

Question 11

The _______________ spectrum that includes the seven types of __________ energy (radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma waves.)

Answer 11

Electromagnetic, Electromagnetic

Question 12

Radio waves

Answer 12

Radio waves are used for communication applications in television, radar, and mobile phones. They have the longest wavelength and the lowest energy.

Question 13

Microwaves

Answer 13

Microwaves are used for satellite signals and cooking.

Question 14

Infrared waves

Answer 14

Infrared waves are used for remote controls, toasters, and night vision cameras.

Question 15

Visible light

Answer 15

Visible light is the only part of the electromagnetic spectrum that humans can see with their naked eye. These waves allow us to see color.

Question 16

Ultraviolet waves

Answer 16

Ultraviolet waves, also called UV rays, are the waves that cause your skin to burn when you spend too much time in the sunlight. UV light waves are also used to sterilize and disinfect items as they are good at destroying bacteria, viruses, and mold.

Question 17

X-rays

Answer 17

X-rays are used in the medical profession to determine broken bones or to see the structure of your teeth.

Question 18

Gamma rays

Answer 18

Gamma rays can be used to treat some forms of cancer. They may also be found in nuclear power plants. These waves have the shortest wavelength and the highest energy.

Question 19

Which electromagnetic wave has the longest wavelength?

Answer 19

Radio wave

Question 20

Which electromagnetic wave has the shortest wavelength?

Answer 20

Gamma wave

Question 21

What wave property increases as the wavelength decreases?

Answer 21

As the wavelength decreases, frequency increases.

Question 22

What happens to the energy as the wavelength decreases?

Answer 22

As the wavelength decreases, the energy increases.

Question 23

What is visible light?

Answer 23

Visible light is a form of electromagnetic radiation. It is the part of the electromagnetic spectrum that is visible to humans and can be separated into the colors of the rainbow.

Question 24

What do you get when you combine all the colors of light?

Answer 24

When all the colors of light from the spectrum are combined, you will get white light or sunlight.

Question 25

Which color of light has the longest wavelength?

Answer 25

Red light has the longest wavelength.

Question 26

Which color of light has the shortest wavelength?

Answer 26

Violet light has the shortest wavelength.

Question 27

What does SAGE stand for?

And what does it measure?

Answer 27

Stratospheric Aerosol and Gas Experiment.

It measures ozone, aerosols, and other particles and gases in the atmosphere.

Question 28

What is the order of the Colors of light in the visible spectrum?

Answer 28

Roy G. Biv.

red, orange, yellow, green, blue, indigo, and violet.
