A source of green laser light has a wavelength of 560nm, what is its frequency? Give your answer to an appropriate number of significant figures and using the correct units.

1.) using the wave speed formula for an electromagnetic wave, c=fλ, (c=3.00x10^8 m/s)

f=c/λ where c=the speed of an electromagnetic wave.

f=(3.00x10^8)/(560x10^-9)= 5.36x10^14 Hz
