Solutions to CBSE Sample Paper - Physics Class 12

a) Draw the graph showing intensity distribution of fringes with phase angle due to diffraction through a single slit. What is the width of the central maximum in comparison to that of a secondary maximum?

b) A ray PQ is incident normally on the face AB of a triangular prism of refracting angle 60 0 as shown in figure. The prism is made of a transparent material of refractive index  Trace the path of the ray as it passes through the prism. Calculate the 2/√3 angle of emergence and the angle of deviation.
