Light from a sodium lamp(S) passes through two Polaroid sheets `P_1` and `P_2` as shown in the figure. What will be the effect of the intensity of the light transmitted
by`P_1` and
by `P_2` on rotating Polaroid `P_1` about the direction of propagation of light? justify your answer in both cases.

Light from an ordianry source(say a sodium lamp) is passed through a polaroid sheet P_1 .The transmitted light is then made to pass through a second polaroid sheet P_2 ,which can be rotated so that the angle (theta) betwen the two polaroid sheets varies from 0^@ to 90^@ .Show graphically the variation of he intensity of light transmitted by P_1 and P_2 as a function of the angle theta .Take the incident beam intensity as I_0 . Why does the light from a cleear blue portion of the sky,show a rise and fall on intesnity,when viewed through a polaroid ,which is rotated?

Fill ups A plane 'p' passes through the point P(1,-2,3). If O is the origin and OPbotp , then equation of the plane p is………….. .

For an ideal gas V - T curves at constant pressure P_(1) & P_(2) are shown in figure, from the figure

Two bulbs are rated (P_1, V) and (P_2, V) . If they are connected (i) in series find the power dissipated in the two combination in terms of P_1 and P_2 ?

A ray of light is sent through the point P(1,2,3) and is reflected on the XY plane. If the reflected ray passes through the point Q(3,2,5) then the equation of the reflected ray is

Find the direction cosines of the line passing through the points P(2,3,5), and Q(-1,2,4).

Consider a light beam incident from air to a glass slab at Brewster's angle as shown in Fig. EP 10.1. A polarised is placed in the path of the emergent ray at point P and rotated about an axis passing through the center and perpendicular to the plane of the polaroid.

Find the equation of a curve passing through the point (1.1) if the perpendicular distance of the origin from the normal at any point P(x, y) of the curve is equal to the distance of P from the x-axis.

Two polaroids P_1 adn P_2 are placed with their pass xes perpendicular to each other.An unpolarised ligth of intensity I_0 is incident on P_1 .a thid polaroid P_3 is kept in betwen P_1 and P_2 such that its axis makes an angle of 60^@ with that of P_1 .determine the intensity of light transited through P_1,P_2 and P_3 .
