c=wavelength*frequency, being c the speed of light
wavelength=3*10^8/1.150*10^15=(3/1.15) * 10^-7=2.6*10^-7 m

First you have the equation C = fλ or V = fλ
where C is the speed of light. which is 3.00 x 10^8
you can use this value because all electromagnetic waves moves at the speed of light it is a constant.
so u isolate of λ
λ = C/f
so λ = 3.00 x 10^8/ 1.150 x 10^15
λ = 2.609 x 10^7 m
