Q

wave speed formula

A

wave speed= frequency x wave length

V = f x (lambda)

17
Q

frequency symbol

A

f

18
Q

frequency definition

A

how many complete waves there are per second measured in hertz (Hz) 1 Hz is one wave per second,

19
Q

frequency equations

A

f = 1 (divided) T

20
Q

period definition

A

is the time it takes (in s) for one complete wave ta pass a point e.g a wave with period 0.002 s has a frequency of 1 (divided) 0.002 = 500 Hz

21
Q

speed symbol

A

(v) for velocity

22
Q

speed definition

A

how fast the wave goes
