From given data set, determine angular dispersion by the prism for extreme colours.
`n_R = 1.622`, `n_V = 1.656` and `delta_R = 2.1^@`
State two conditions for total internal reflection.

From the given data set, determine angular dispersion by the prism and dispersive power of the material for extreme colours. n_R = 1.62, n_v = 1.66, s_R = 3.1^@

The angular dispersion produced by a prism of angle 5^@ is [n_V = 1.665, n_r = 1.645]

The angular dispersion produced by a prism of angle 5^@ is [mu_v = 1.665, mu_r = 1.645]

For a dense flint glass prism of refracting angle 10^0 , Findthe anangular deviation for extreme colours and the dispersive ppower for dense flint glass. (n_(red) = 1.712 , n_(violet) = 1.792 )

Write sample space 'S' and number of sample point n(S) for each of the following experiments. Also write events P, Q, R in the set form and write n(P), n(Q), n(R). From three girls and one boy, committee of two persons is to be formed . Condition for event P : There must be at least one boy in the committee. condition for event Q : There must be two girls in the committee.

For a dense flint glass prism of refracting angle is 10^@ , obtain angular deviation for extreme colours and dispersive power for dense flint glass. (n_(red) = 1.712, n_(viol et) = 1.792)
