Humans have three types of cone cells in their eyes, which are responsible for color vision. Each type absorbs a certain part of the visible spectrum. Suppose a particular cone cell absorbs light with a wavelength of 430nm. Calculate the frequency of this light.

    6.97 E 16

    Explanation:

    Frequency is a function of velocity of light to it's wavelength.

    Mathematically written as

    F = Velocity / wavelength

    Velocity of light = 3 x 10^8

    Wavelength = 430 nm = 430 x 10^-9 m

    converting wavelength from nanaometer to meter we divide by 10^9

    Frequency = (3 x 10^8) / (430 x10^-9) = 6.97 E 16
