Light as wave

Light is a wave (an electromagnetic wave)  and  thus  light has a wave length , frequency and  speed.

It holds:  

 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

c=f λ

3.00 x 108=(5.60 x 10-7)f

f = 5.36 x 1014 Hz
