A monochromatic ray of light passes from air to glass. The wavelength of light in air is λ, the speed of light in air is c and in glass is V. If the absolute refractive index of glass is 1.5, write down

  1. the relationship between c and V,
  2. the wavelength of light in glass.

उत्तर

aμg = 1.5, aμg = `"speed of light in air"/"speed of light in glass" = c/V`

  1. μ or c = aμ× V = 1.5 V
  2. aμ= `"wave length of light in air"/"wave length of light in glass"`

∴ wave length of light in glass = `λ/ 1.5`
