Transcribed Image Text:

The intensity distribution of a red led on an absorbing layer of material is a Gaussian centred at the wavelength λo = 660nm & width = 20nm. If the absorption coefficent vasies with wavelength as xo-K(A-to) where Lofk are the constants, the light emerging from the observer will as a) Blue shifted retaining the gausian intensity distribution. Blue shifted with a symmetric intensity dis bibution C) Red shifted retaining the gausian intensity distribution d) Red shifted with an asymmetric intensity distribution.
