is there any formula that can determine the new wavelength of light when it enters glas,provided that wavelength in air and refractiveindex of the medium are given?

Expert Answer:

Dear student,
 

Refractive index, n = c / v
In air :


Frequency = Speed / Wavelength = 5 x 10^14 Hz

Frequency does not change when light enters from one medium to another as it depends upon the source.

So
frequency in glass = 5 x 10^14 Hz

Wavelength = Speed / Frequency 

Hope this helps.

Thankyou
