Title: Apparent Depth
Post by: mengue on November 29, 2005, 05:43:14 pm
If an object is positioned 1m under water, and a man is positioned above the water with a angle of 30º , what is the equation to solve the apparent depth problem?

n1 sin(c1) = n2 sin(c2)

1 sin (pi/6) = (4/3) sin (c2)

sin(c2)=3/8 , from the depth is 1 m you will find the location.
