** 4. A beam of light travels vertically downward and strikes a horizontal mirror, reflecting directly back vertically upward, as indicated by the black dashed line in the diagram at left. The mirror is now rotated, so that it is 10° away from horizontal, as is the red mirror in the diagram. The incident solid black ray is the same in both cases. a) At what angle from the vertical will the reflected beam (the red dashed arrow) now ' 10° be seen? b) If the mirror is further rotated until it is 20° from the horizontal, what will be the new angle between the reflected beam and the vertical?

A beam of light is incident from air on the surface of a liquid. If the angle of incidence is 36.2° and the angle of refraction is 25.0°, find the critical angle for the liquid when surrounded by air.
