A certain ultraviolet light has a wavelength of 160nm in carbon di-sulfide (refractive index = 1.6). The wavelength of the same light in diamond (refractive index = 2.4) will be
Group of answer choices
83 nm.
107 nm.
160 nm.
200 nm.
240 nm.
Wavelength of light in carbon di-sulphide, λc = 160 nm
Wavelength of light in air, λ = n x λc =1.6 x 160 = 256 nm
Wavelength of light in diamond, λd = λ/nd = 256/2.4 = 106.7 = 107 nm
Wavelength of light in diamond, λd = 107 nm
