Wave length of light whose time period is 3×10^-10

1.	Wave length of light whose time period is 3×10^-10
Answer» velocity = frequency * WAVELENGTH and TIME period = 1/frequency so wavelength = velocity * time period =(310^8) (310^-10) =9 10^-2

Answer»

velocity = frequency * WAVELENGTH

and TIME period = 1/frequency

so wavelength = velocity * time period

=(3*10^8) * (3*10^-10)

=9 * 10^-2
