Waves

Question 1

Wave

Answer 1

a disturbance that transfers energy from place to place

Question 2

Energy

Answer 2

ability to do work

Question 3

Medium

Answer 3

material a wave travels through - can be solid, liquid, or gas

Question 4

Does a medium move with a wave

Answer 4

no, the particles vibrate while the waves go through

Question 5

All waves need

Answer 5

energy

Question 6

Mechanical wave

Answer 6

wave that travels through a medium

Question 7

Electromagnetic wave

Answer 7

wave that travels through a VACUUM
(empty space)

Question 8

Transverse wave

Answer 8

wave that move up/down

Question 9

Top part of a transverse wave

Answer 9

crest

Question 10

Bottom part of a transverse wave

Answer 10

trough

Question 11

Longitude wave

Answer 11

wave that moves like a spring cursive L

Question 12

Rarefaction (longitudinal wave)

Answer 12

spread out spring wave

Question 13

Compression (longitudinal wave)

Answer 13

coiled up spring wave

Question 14

Amplitude definition

Answer 14

amount of energy from resting position

Question 15

Amplitude measuring in transverse wave

Answer 15

crest to crest or trough to trough (crest to resting position)

Question 16

Amplitude measuring in longitudinal wave

Answer 16

of compression waves

Question 17

Wavelength definition

Answer 17

distance between 2 parts of the wave

Question 18

Wavelength measuring in transverse wave

Answer 18

crest to crest or trough to trough

Question 19

Wavelength measuring in longitudinal wave

Answer 19

distance between two compressions

Question 20

Frequency definition

Answer 20

of waves that pass a point at a given time

Question 21

Frequency measured in

Answer 21

Hertz

Question 22

Speed

Answer 22

how fast a wave travels

Question 23

Speed equation

Answer 23

speed = wavelength (frequency)

Question 24

Reflection

Answer 24

wave bounces off an object

Question 25

Law of reflection

Answer 25

angle of incidence = angle of reflection

Question 26

Refraction

Answer 26

wave changes speed due to change in medium

Question 27

Refraction only occurs

Answer 27

when wave enters new medium at an angle

Question 28

Rainbows explanation

Answer 28

raindrops in the air & light passes through it different angle and spreads out the ROYGBIV colors

Question 29

Diffraction

Answer 29

waves move around or through a barrier

Question 30

Constructive interference

Answer 30

2 waves combined and increase the amplitude

Question 31

Destructive interference

Answer 31

2 waves combined to decrease the amplitude

Question 32

Seismic waves

Answer 32

p waves (longitudinal waves) + s waves (transverse waves)+surface waves to cause destruction
