Answer 14

Light and ocean waves

Question 15

List examples of compression

Answer 15

Sound

Question 16

What are sound waves

Answer 16

Vibrations are sent out which cause particles to hit each other

Question 17

Speed of sound through solids

Answer 17

Very fast because atoms are very close to each other

Question 18

Speed of sound through liquids

Answer 18

Middle-atoms are further away from each other

Question 19

Speed of sound through gas

Answer 19

Gas: slow-atoms are far away from each other

Question 20

Relationship for of frequency and pitch

Answer 20

Lower pitch= lower frequency

High pitch= high frequency

Answer 24

The maximum distance moved from point on a vibrating body or wave measured from it’s equilibrium position

Question 25

What is pitch

Answer 25

How high or low a note is played

Question 26

What is compression

Answer 26

The area in a wave where the particles are closest together

Question 27

The electromagnetic spectrum

Answer 27

``` Gamma Rays X-rays Ultraviolet Visible light Infrared Microwaves Radio ```

Question 28

What does absorption mean

Answer 28

H

Question 29

What does absorption mean

Answer 29

What does absorption mean the process by which one thing absorbs or is absorbed by another

Question 30

What does scattering mean

Answer 30

When light or other energy waves pass through an imperfect medium

Question 31

What does reflection mean

Answer 31

The throwing back by body or surface of light,heat, or sound without absorbing it

Question 32

What is refraction

Answer 32

Being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density

Question 33

What is the law of reflection

Answer 33

States that the incident ray, the reflected ray and the normal to the mirror all lie on the same plane

Question 34

Why does refraction occur

Answer 34

Light follows the principle of least action which means it takes the future route which is to bend
