Question

Let c 3.00 x 108 m/s he eye is most sensitive to light with a frequency of 5.45 x 1014Hz. What is he wavelength of this light? What would its color be?

Answer 1

Step-by-step explanation:

It is given that,

Frequency of the wave,
`f=5.45* 10^(14)\ Hz`

We need to find the wavelength of an EM wave. The wavelength of the light is given by :

`\lambda=(c)/(f)`

c is the speed of light

`\lambda=(3* 10^8\ m/s)/(5.45* 10^(14)\ Hz)`

`\lambda=5.5045* 10^(-7)\ m`

or

`\lambda=550.46\ nm`

So, the wavelength of light is
`\lambda=550.46\ nm`. This is the wavelength of green light. Hence, this is the required solution.
