Deviation produced by a triangular prism; dependence on colour (wavelength) of light; dispersion and spectrum
Fig 6.12 shows a thin beam of white light from a source S striking on one face of a prism.
What conclusion do you draw from the observation in part (b) above?
How does the deviation produced by a triangular prism depend on the colours (or wavelengths) of light incident on it?
If a monochromatic beam of light undergoes minimum deviation through an equiangular prism, how does the beam pass through the prism, with respect to its base?
