How are sound waves produced?
First an object makes a sound by vibrating. The vibrations then pass through air by making air molecules vibrate. These vibrations are then picked up by the ear.
1 of 9
Amplitude:
It is the distance between the peak and undisturbed part of the wave. The bigger the amplitude the louder the volume.
2 of 9
Frequency:
The frequency of a wave is the number of waves produced by a source each second. It is also the number of waves that pass a certain point each second
3 of 9
Wavelength:
The wavelength of a wave is the distance between a point on one wave and the same point on the next wave. The wider the wavelegth the deeper the lower the sound, and vice versa.
4 of 9
Emit:
To give out
5 of 9
Transmit:
When light or another radation passes through an object.
6 of 9
Convex Mirrors:
The center curves towards the source of light, they are called DIVERGING mirrors.
7 of 9
Concave Mirrors:
The centre curves away from the source of light they are called CONVERGING mirrors.
8 of 9
Formula for Speed:
Speed = Distance/Time
