Unit 5&6: Wave Properties and Behaviors

Question 1

The highest point on a wave.

Answer 1

Crest

Question 2

The lowest point on a wave.

Answer 2

Trough

Question 3

The measure of the amount of energy it carries.

Answer 3

Amplitude

Question 4

The distance from the crest or trough to the resting point.

Answer 4

wavelength

Question 5

A measure of the number of waves that pass a point in a given amount of time.

Answer 5

Frequency

Question 6

What is the definition of a wave?

Answer 6

Transfer of Energy from one location to anthor

Question 7

What are the 2 main types of waves?

Answer 7

Electromagnetic and Mechical

Question 8

What kind of wave needs a medium to travel?

Answer 8

Mechical

Question 9

What is the definition of a medium?

Answer 9

Matter through which the wave travels

Question 10

How do the particles of a medium move when a wave passes through them?

Answer 10

As particles vibrate, they pass the energy of the disturbance from one particle to the next which then passes energy to the particles next to them.

Question 11

Which wave can move through empty space?

Answer 11

Electromagnetic

Question 12

An electromagnetic wave can only travel as what wave?

Answer 12

Transverse

Question 13

How does the medium of a transverse wave move in reference to the direction of the energy?

Answer 13

Particles of the medium move perpendicular to the direction of the wave.

Question 14

How does the medium of a longitudinal wave move in reference to the direction of energy?

Answer 14

Moves back and forth in the same direction as the wave travels.

Question 15

Electromagnetic waves are waves that consist of vibrating _________ and _________________ particles.

Answer 15

Electric and Magnetic field

Question 16

What are the 4 main wave interactions/behaviors?

Answer 16

Absorption, Reflection, Refraction and Transmission

Question 17

If a wave hits a mirror at a 60-degree angle, what degree of angle does the wave bounce off of the mirror?

Answer 17

60

Question 18

Refraction occurs because a wave goes from one _______ to another.

Answer 18

Medium

Question 19

Mediums with different states of matter have different ________, which causes the speed of the wave to speed up or ________ down.

Answer 19

Densities, Slow

Question 20

What is Reflection?

Answer 20

When a wave strike off an object and bounces off

Question 21

What is Refraction?

Answer 21

When waves bend as they enter a new medium at an angle

Question 22

What is absorption?

Answer 22

When waves don’t move through or reflect off of a medium. The waves are absorbed and the energy is TRANSFERED into the medium.

Question 23

What is transmission?

Answer 23

Some waves have the ability to pass through a medium with little change to the wave using a property, called transmission

Question 24

Describe what a Longtudienial wave looks like.

Answer 24

Like a Slinky

Question 25

Describe what a Transverse wave looks like.

Answer 25

Like a wave

Question 26

Provide a real-life example of the wave behaviors (ANSWERS WILL VARY!)

Answer 26

Reflection- Light shining off of a mirror
Refraction- Pencil in water
Absorption- Extreme heat on Pavement
Transmission- Cell phone signals coming through your walls to your phone.
