Question
A beam of white light is incident on hollow prism of glass as shown in figure. Then :
- the light emerging from prism gives no dispersion
- the light emerging from prism gives spectrum but the bending of all colours is away from base.
- the light emerging from prism gives spectrum, all the colours bend towards base, the violet the most and red the least.
- the light emerging from prism gives spectrum, all the colours bend towards base, the violet the least and red the most.
The correct answer is: the light emerging from prism gives no dispersion
