Phenomenon of a wave bouncing off a surface

25
Q

When a waves speed changes as it moves though a boundary between different media

A

refraction

26
Q

A

interference

27
Q

When two waves join to form a larger wave

A

constructive interference

28
Q

The internetaction of interfering waves resulting in a waveform with a smaller amplitude than those of the interfering waves

A

destructive interference

29
Q

A waveform whose nodes appear to be stationary

A

standing waves

30
Q

Node

A

nodes point in a standing wave that experiences on vertical displacement

31
Q

When two waves combine to form a large wave

A

beat

32
Q

When a wave moves around a corner

A

diffraction

33
Q

The frequency differs if the receiving end is moving

A

Doppler effect

34
Q

What is the mathematical relationship between an oscillating systems period and it’s frequency? What are the standard units for period? For frequency?

A

It Is he same. Seconds. Hertz

35
Q

How does the mass of an oscillating system generally affect it’s frequency?

A

It decreases it

36
Q

What happens to the amplitude of a real world periodic oscillations over time?

A

They slow down

37
Q

Wha happens to an oscillating systems amplitude when it beings to resonate? What limits a resonating systems amplitude?

A

It stays the same. The energy coming in.

38
Q

Describe the parts of an ideal pendulum.

A

The pivot point the arm and the mass at the end of the pendulum.

39
Q

Who was the first European scientist who studied the pendulum?

A

Galileo

40
Q

What factors affect the period of a pendulum? What property of a pendulum does not affect its period?

A

The length of the arm. It’s weight.

41
Q

What two factors determine wave speed? Why does the speed of a wave on the surface of water differ from the speed of a sound wave in water

A

Wave length and frequency. Because sound travels faster in water than air

42
Q

Describe the two kinds of mechanical waves.

A

When the vibration is at right angles to the direction of travel the wave is a transverse wave. I’d the vibration is parallel to the direction of wave movement it is a longitudinal wave.

43
Q

In what two ways can a wave bend?

A

There is only one diffraction
