Question

An underwater scuba diver sees the Sun at an apparent angle of 44.0 degree from the vertical. What is actual direction of the Sun? A laser beam is incident at an angle of 28.6 degree to the vertical onto a solution of corn syrup in water. (a) If the beam is refracted to 18.92 degree to the vertical, what is the index of refraction of the syrup solution? (b) Suppose the light is red, with wavelength 632.8 nm in a vacuum. Find its wavelength in the solution. (c) Find its frequency in the solution. (d) Find its speed in the solution.

Explanation / Answer

as per chegg guidelines i can answer only one.Please raise different question for others

1)n1=1.0 for air
n2=1.33 for water

theta=44 degrees

1sin=1.33sin44

=67.5 degrees

90-67.5

=22.5o
