Answer #1

we have given the angle 10° and final intensity =0.3I°.

From the law of males,   ,

and    57° so angle from the vertical will be 57+10= 67°

    The polarization of a helium-neon laser can change with time. The light from a 1.5 mW laser is initially horizontally polarized; as the laser warms up, the light changes to be vertically polarized. Suppose the laser beam passes through a polarizer whose axis is 35 ∘ from horizontal. By what percent does the light intensity transmitted through the polarizer decrease as the laser warms up?
