At what incident angle, with respect to the normal to the interface, is light inside the crown glass completely polarized when reflected from water

57°

Explanation:

Etienne Malus discovered the idea of polarization by reflection. If light is incident on a surface at an angle of 57°, the reflected ray is found to be plane polarized.

Hence, with respect to the normal to the interface, light incident at 57° is completely polarized.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
