CBSE Class 12-science Answered

Draw a graph showing the variation of angle of deviation ‘δ’ with that of angle
of incidence ‘i’ for a monochromatic ray of light passing through a glass prism
of refracting angle ‘A’. What do you interpret from the graph? Write a relation
showing the dependence of angle of deviation on angle of incidence and hence
derive the expression for refractive index of the prism.

Calculate the value of θ, for which light incident normally on face AB grazes

along the face BC. μg = 3/2 μw = 4/3.

begin mathsize 14px style We space know space that comma sinθ equals straight mu subscript straight w over straight mu subscript straight g equals fraction numerator begin display style 4 over 3 end style over denominator begin display style 3 over 2 end style end fraction equals 4 over 3 cross times 2 over 3 equals 8 over 9 therefore straight theta equals sin to the power of negative 1 end exponent open parentheses 8 over 9 close parentheses end style
 
NOTE: Kindly ask the other questions as separate queries.
