Waves

Question 1

Define transverse waves

Answer 1

Waves that vibrate or oscillate perpendicular to the direction of energy transfer

Question 2

Define Longitudal waves

Answer 2

Waves the oscillate or vibrate parallel to the direction of energy transfer

Question 3

Examples of transverse waves

Answer 3

Light
Ripples on water

Question 4

Examples of longitudinal waves

Answer 4

Sound
Tsunami waves

Question 5

Define amplitude

Answer 5

The highest a particle is displaced from its equilibrium position

Question 6

Define wavelength

Answer 6

The distance between a particular point on a wave and that same point on the next

Question 7

Define frequency

Answer 7

The number of waves that pass a point per second

Question 8

Time period

Answer 8

The time taken for one complete wave to pass a point

Question 9

How do waves transfer energy

Answer 9

Waves can transfer energy by oscillating without moving

Question 10

Doppler effect

Answer 10

Ahead of a car wavefronts are compressed. Short wavelength, high frequency.
Behind a car wavefronts are stretched. Long wavelength, low frequency

Question 11

All waves can be refracted and reflected

Answer 11

Yes.

Question 12

Total internal reflection

Answer 12

She light is moving from a denser medium to a less dense one, instead of being refracted, all light is reflected

Question 13

Critical angle

Answer 13

Angle of incidence that produces an angle of refraction of 90degrees
