Light is a wave (an electromagnetic wave) and thus light has a wave length , frequency and speed.
λ = c/f of c=f λ
- c speed of light in m.s-1
- f frequency in Hz
- λ wave length in m c en λ depends on the medium
A certain kind of light has in vacuum (air) a wave length of 5.60 x 10-7 m.
Find the frequency
3.00 x 108=(5.60 x 10-7)f
f = 5.36 x 1014 Hz
