Waves

Question 1

Define transverse waves

Answer 1

When the particles move up and down so the direction of their movement is at a right angle to the direction of the wave

Question 2

Define wavelength

Answer 2

the distance between 2 matching points on neighbouring waves

Question 3

Define amplitude

Answer 3

Maximum distance a point moves from from its rest position

Question 4

Define the amplitude of a transverse wave

Answer 4

Height of a peak or trough from the waves rest position

Question 5

Define frequency

Answer 5

Number of waves passing any point each second

Question 6

Define longitudinal waves

Answer 6

The particles vibrate back and forth so the direction of their movement is parallel to the direction of the wave

Question 7

Define compression

Answer 7

Sections that are pushed together

Question 8

Define refraction

Answer 8

Sections that are stretched out

Question 9

Frequency equation

Answer 9

Frequency = velocity/ wavelength

Question 10

Wave speed equation

Answer 10

V = f x wavelength
