Archerfish are able to shoot down bugs up to three meters above
the water surface thanks to their excellent eyesight and ability to
compensate for refraction. A biologist is studying how well the
archerfish can adjust for water temperature, which has a small but
measurable effect on the index of refraction of water. As part of
that, the biologist wants to know very precisely what the
refraction angle will be when a light ray is incident from air into
water with an index of refraction of n = 1.346,
at an incident angle of 15.00°. What is this refraction angle at
four significant figures? State your answer in degrees rounded to
the nearest hundredth of a degree.
