Prism angle of a prism is`10^(@)`,Their refractive index for red&violet colour is `1.51&1.52`respectively .Then dispersive power will be
`(1) 0.5, (2)0.15, (3)0.019,(4) 0.032`

Text Solution

Verified by Experts

Despersive power of prism
`omega=((mu_(v)-mu_(r))/(mu_(y)-1))`
but`mu_(y)=(mu_(v)-mu_(r))/(2)=(152+151)/(2)=1.515`
therefore`omega=(1.52-1.51)/(1.515-1)=(0.1)/(1.515)=0.019`
