Question

A narrow beam of light from a laser travels through air (n = 1.00) and strikes point A on the surface of the water (n = 1.33) in a lake. The angle of incidence is 52°. The depth of the lake is 3.6 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 lake-bottom? m (b) Considering refraction, how far away from point B would the laser beam strike the lake-bottom? m

Step 1

Given: Angle of incidence (I) = 52°, depth of the lake (d) = 3.6 m Using the formula: \( \tan(I) = \frac{D}{d} \) Substitute the values: \( \tan(52°) = \frac{D}{3.6} \) \( D = 3.6 \times \tan(52°) \) \( D = 3.6 \times 1.2799 \) \( D = 4.6076 \, m \) Show more…
