Λ= V/f 
<span>but change it to represent the speed of light, c </span>
<span>λ= c/f </span>
<span>c = 3.00 x 10^8 m/s </span>
<span>Plug in your given info and solve for λ(wavelength) </span>
<span>λ= 3.00 x 10^8 m/s / 7.5 x 10^14 Hz
(3.00 x 10^8) / (7.5 x 10^14) = 300,000,000 / 750,000,000,000,000 = 0.0000004
Hope this helps :)

Wavelength of any wave = (speed of the wave) / (frequency)

Speed of light in vacuum = 3 x 10^8 m/s

Wavelength =  (3 x 10^8) / (7.5 x 10^14)  =<em>  4 x 10^-7 m</em>  (400 nanometers)
