Electromagnetic waves
4
Q
Examples of longitudinal wave
A
P wave
Sound waves
5
Q

A
Require a medium
6

A
Can travel through a vacuum
7
Q
Frequency
A
1 / T
8
Q
Time
A
1 / f
9
Q
equation of speed of waves
A
v = fλ
10
Q
deep water
A
- more wavelength
- more speed
- same frequency
- more angle
11
Q
shallow water
A
- less wavelength
- slower
- same frequency
- less angle
12
Q
Diffraction
A
After diffraction, speed, wavelength and frequency stays the same
more diffraction = smaller gap
