Anarrow beam of light from a laser travels through air (n = 1.00) and strikes the surface of the water (n = 1.33) in a lake at point a. the angle of incidence is 58 degrees. the depth of the lake is 2.9 m. on the flat lake-bottom is point b, directly below point a. (a) if refraction did not occur, how far away from point b would the laser beam strike the lakebottom? (b) considering refraction, how far away from point b would the laser beam strike the lake-bottom?
