What is snell law

Polarizer and analyzer are set with their polarizing directions parallel, so the intensity
of transmitted light is maximum. Through what angle should either be turned, so that
intensity be reduced to 75% of the maximum intensity?

A convex lens of focal length 20 cm is placed after a slit of width 0.6 mm. If a plane wave of wavelength 600 nm falls normally on a slit, calculate the separation between the second minima on either side of the central maximum. Calculate the ratio of the intensity of the principal maximum to the first maximum on either side of the principal maximum.

A grating (with 15,000 lines per inch) is illuminated by sodium light. The grating spectrum is observed on the focal plane of a convex lens of focal length 10 cm. Calculate the separation between the D1 and D2 lines of sodium (The wavelengths of D1 and D2 lines are 589.0 and 589.6 nm respectively).

A hammer falls from a shelf and strikes the ground at 12 ms . Using kinetic
and potential energies in the calculation, determine what height did it fell from.
