The wavelength of light in vacuum is ` lambda `. The wavelength of light in a medium of refractive index n will be

If the wavelength of light in vacuum be lambda , the wavelength in a medium of refractive index n will be

If the wavelength of light in vacuum be lambda , the wavelength in a medium of refractive index n will be

When light moves from one medium to another (i) the frequency of light remains same and wavelength changes (ii) refractive index of a medium is the ratio of speed of light in vacuum and speed of light in medium (iii) refractive index of a medium is the ratio of wavelength of light in vacuum and wavelength in medium (iv) for denser medium, the value of refractive index is larger

The wavelength of light in vacuum is 6000 A^(@) and in a medium it is 4000 A^(@) The refractive index of the medium is:

The wavelength of light in vacuum is 6000 A^(@) and in a medium it is 4000 A^(@) The refractive index of the medium is:

A wavelength of a monochromatic light in vacuum is lambda . It travels from vacuum to a medium of absolute refractive index mu . The ratio of wavelength of the incident and refracted wave is
