What is the wavelength of violet light?

Red light of wavelength 6400 overset@A in air, has a wavelength of 4000 overset@A in glass. If the wavelength of violet light in air is 4400 overset@A , what is the wavelength in glass. (Assume R.I. for violet and red colour are same)

Red light of wavelength 6400 Å in air has a wavelength of 4000 Å in glass. If the wavelength of violet light in air is 4400 Å, then the wavelength in glass is

Statement I : Critical angle of the light passing from glass to air is minimum for violet colour. Statement II : The wavelength of violet light is greater than the light of other colours.

Wavelength of red colour is approximately how many times the wavelength of violet colour ?

Assertion : Critical angle of light while passing from glass to air is minimum for violet colour. Reason : The wavelength of violet li^ht is greater than that of other colours
