Waves

Question 1

Different name for longitudinal wave

Answer 1

Compression wave

Question 2

Example of longitudinal wave

Answer 2

Sound wave

Question 3

Example of a transverse wave

Answer 3

String being moved up & down

Question 4

What is a longitudinal wave?

Answer 4

Wave when the movement of the wave is moving along the same axis as the movement

Question 5

What is a transverse wave?

Answer 5

Wave which moves transverse (opposite) of the medium

Question 6

What is the amplitude of a wave?

Answer 6

Height from rest to peak

Question 7

What is the period of a wave?

Answer 7

Time it takes for one cycle

Question 8

What is the frequency of n wave?

Answer 8

Number of cycles per second

Question 9

Frequency =?

Answer 9

f = 1/ T
T = period

Question 10

What is the wave length?

Answer 10

Distance from peak to peak or the like
Distance of 1 cycle

Question 11

How do you calculate velocity of a wave?

Answer 11

V= lambda / T = lambda * f

Question 12

What is a node of a standing wave?

Answer 12

A point that doesn’t move

Question 13

What happens when a wave is reflected off a node?

Answer 13

It flips directions

Question 14

How many nodes in the 2nd harmonic wave?

Answer 14

3

Question 15

How many nodes in the 3rd harmonic wave?

Answer 15

4

Question 16

What are the nodes on a standing wave?

Answer 16

Destructive, where the wave cancels

Question 17

What are the anti-nodes of a standing wave?

Answer 17

Maxima of wave
Where there is the most motion

Question 18

How do you find the wave length of a harmonic? (Standing wave)

Answer 18

Lambda n= (2*L)/n
L= length of string

Question 19

What is the total wave during wave interference?

Answer 19

The 2 waves added

Question 20

What happens to frequency when temperature increases?

Answer 20

Frequency decreases
