5.1 Waves

Question 1

What is amplitude

Answer 1

The distance from the middle to the top of the wave

Question 2

What is Frequency

Answer 2

Number of waves/oscillations per second

Question 3

what is wavelength

Answer 3

Distance from one point of a wave to the same point on the next wave

Question 4

what is time period

Answer 4

the time for one wave to pass a point

Question 5

What is the difference in transverse and longitudinal waves

Answer 5

sound waves are longitudinal and their direction of vibration is the same direction as the waves. In transverse waves the direction of vibration is at right angles to the direction of the travel of the wave.

Question 6

How do you model waves?

Answer 6

Ripples on water waves model transverse waves. If u place a small object you can tell the wave travels and not the water,

Question 7

What happens when a wave travels between mediums?

Answer 7

The velocity and direction may change but a refraction occurs

Question 8

What happens to the wavelength of a sound wave when it moves between mediums?

Answer 8

It will move away from a line at 90 degrees to the surface which increases the wavelength of the soundwave.

Question 9

what can happens to a sound wave at a boundary?

Answer 9

it can be reflected (echo), transmitted or absorbed

Question 10

What happens to frequency of a sound wave when it moves between mediums?

Answer 10

stays the same
