Answer 2

Electromagnetic
Mechanical

Question 3

Vibration of particles in a transverse wave?

Answer 3

The particles oscillate perpendicular to the direction of energy transfer

The speed of a wave is determined by its __________ and __________.

Answer 4

frequency; wavelength

Question 5

formula for wave speed?

Answer 5

Wave speed (v) = frequency (f) × wavelength (λ)

Answer 6

longitudinal

Question 7

Vibration of particles in a longitudinal wave?

Answer 7

The particles oscillate parallel the direction of energy transfer

Question 8

What is wavelength?

Answer 8

Wavelength is the distance between two consecutive points in phase on a wave (crest to crest)

Question 9

Frequency is the number of complete waves passing a point in a given time
(Hertz ,Hz)

Question 10

In which medium does sound travel fastest?

Answer 10

Solids

Question 11

What is amplitude?

Answer 11

maximum displacement of points on a wave from their rest position

Question 12

What determines the loudness of a sound wave?

Answer 12

Amplitude

Question 13

What affects the pitch of sound?

Answer 13

Frequency

Question 14

relationship between wavelength and frequency

Answer 14

Indirectly proportional

Question 15

True or False: Electromagnetic waves require a medium to travel.

Answer 15

False

Question 16

What is the Doppler effect?

Answer 16

change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Question 17

The __________ of a wave is a measure of its energy.

Answer 17

amplitude

Question 18

What is a wave pulse?

Answer 18

A wave pulse is a single disturbance or a short burst of energy traveling through a medium.

Question 19

What are the two main types of progressive waves?

Answer 19

Transverse waves and longitudinal waves.

Question 20

What is the effect of tension on the speed of a wave on a string?

Answer 20

Increasing the tension in a string increases the speed of the wave.

Question 21

What is the relationship between period and frequency?

Answer 21

Period (T) is the reciprocal of frequency (f); T = 1/f.

Question 22

What happens to the wavelength of a wave if its speed increases while frequency remains constant?

Answer 22

The wavelength increases.
