Q

What creates sound?

A

Vibration

26
Q

What does the speed of sound depend on?

A

Medium

27
Q

What does the loudness of a sound depend on?

A

Amplitude of the sound wave

28
Q

What does the pitch of a sound depend on?

A

The frequency of the sound wave

29
Q

When do standing waves occur?

A

When waves of identical frequencies interfere with each other while traveling in opposite directions on the same medium

30
Q

What are beats?

A

Beats occur when two sounds with similar frequencies interfere, this results in alternating quiet and loud sounds. The beat frequency is always the difference between the two frequencies of the waves.

31
Q

What are mechanical and electromagnetic waves?

A

Mechanical waves need a medium to travel while electromagnetic don’t

32
Q

What is frequency measured in?

A

Hertz

33
Q

What is superposition?

A

The displacement of a medium caused by 2 or more waves.

34
Q

What is light?

A

A rang of frequencies on the electromagnetic spectrum that stimulate the eye

35
Q

How fast does light travel?

A

3x10⁸

36
Q

What are the frequencies on the electromagnetic spectrum?

A

Radio Micro Infrared Visible Ultraviolet Xray Gamma

37
Q

What is the law of reflection?

A

The angle of incidence is equal to the angle of reflection

38
Q

What is refraction?

A

When light changes mediums

50
Q

What are the 4 factors that affect resistance?

A
  1. Length of wire (increases, increases resistance)
