Question

A ray of light of frequency 5×10^14 Hz is passed through liquid the wavelength of light measure in liquid is 450×10^-9calculate refractive index

Answer 1

Answer:

1.33

Explanation:

 Given A ray of light of frequency 5×10^14 Hz is passed through liquid the wavelength of light measure in liquid is 450×10^-9 calculate refractive index

        We know that  λ = c / n x f

               So  450 x 10^-9 = 3 x 10^8 / n x 5 x 10^14

                    450 x 10^-9 n x 5 x 10^14 = 3 x 10^8 x 10^-5

                          n = 3 x 10^8 x 10^-5 / 450 x 10^-9  x 5 x 10^14

                        n = 1.33

So refractive index n will be 1.33
