Two monochromatic rays of light are incident normally on the face AB of an isosceles right-angled prism ABC.The refractive indices of the glass prism for the two rays 1 and 2 are respectively 1.35 and 1.45[Fig.2.76]Trace the path of these rays after entering through the prism .

Two parallel plate capacitors A and B have the same separation d= 8.85xx10^-4m between the plates. The plate area of A and B are 0.04m^2 and 0.02m^2 respectively. A slab of dielectric constant (relative permittivity) K=9 has dimensions such that it can exactly fill the space between the plates of capacitor B. A is then charged to a potential difference of 110V. Calculate the capacitance of A and the energy stored in it.
