Refractive index of air is `1.0003.` The correct thickness of air column which will have one more wavelength of yellow light `(6000 Å)` than in the same thickness in vacuum is

The wavelength of yellow light in vacuum is 6000 Å. If the absolute refractive index of air is 1.0002, then calculate the thickness of air column which will have one more wavelength of yellow light than in the same thickness of vacuum.

Wavelength of blue in vacuum is 5000 Å . What will be the thickness of an air column of same thickness which have 20 more wavelengths of blue light ? Given the refractive index of air column is 1.003.

The refractive index of glass plate is 3/2 . Then the correct thickness of glass plate that will permit the same number of wavelengths as that by an 18 cm long column of water is (mu_(w)=4/3)

The difference in the number of waves when yellow light propagates through air and vacuum columns of the same thickness is one. The thickness of the air column is___________mm. [Refractive index of air = 1.0003, wavelength of yellow light in vacuum = 6000Å

The refractive index of certain glass is 1.5 for light whose wavelength in vacuum is 6000Å . The wavelength of this light when it passes through glass is:

The refractive index of a certain glass is 1.5 for light whose wavelength in vacuum is 6000 Å. The wavelength of this light when it passes through glass is

(a) Find the refractive index of glass with respect to water. Given : mu_(gw)=(3)/(2) "and" mu_(w)=(4)/(3) . (b) A source of yellow light placed in air is observed by a person swimming under water. If the wavelength of yellow light in air is 6000 Å , then find its speed, wavelength and colour as observed by the person.

A parallel beam of white of white light falls on a thin film whose refractive index is 1.33. If angle of incidence is 52^(@) then thickness of the film for the reflected light to be coloured yellow (lambda=6000Å) most intensively must be :

Refractive index of a thin soap film of a uniform thickness is 1.38. The smallest thickness of the film that gives an interference maxima in the reflected light when light of wavelength 5520 Å falls at normal incidence is
