A) For the rectangular glass prism, plot: (1) A graph of Sin i against Sin r. Measure the slope.
(it) A graph of i against r, measure the slope.
(iii) A graph of Sini Sin r against Sin r. Measure the slope.
(iv) b) For the triangular prism, plot:
() (1) A graph of D against i and measure the value of the minimum deviation
Dm.
(vi) (ii) A graph of D against (i + e) and measure the intercept A on both axes.
From the relation Sin (A+D=n
2
Sin A
2.
Where = A refracting angle of the prism. Obtain the value of n.
