d A person with a height of 1.4 meters stands at the edge of a lake that is 2.8 meters deep, d = 2.8 m. A snapping turtle appears to be 3.4 meters from the edge of the lake. Note that the dotted lines show were the light appears to be originating, that is, where the image of the turtle is formed. The light is coming from the turtle, through the water, refracting into the air, and then to the person on the shore What is the angle of refraction for the light . degrees Submit Answer Tries 0/2 The index of refraction for the water in this lake is n = 1.4. What is the angle of incidence? degrees Submit Answer Tries 0/2 What is the distance from the edge of the lake to the point where the light is crossing from the water into the air? meters Submit Answer Tries 0/2 What is the actual distance from the lake edge to the turtle? meters Submit Answer Tries 0/2

Suppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of 45.0° with respect to the normal, and you observe the angle of refraction to be 40.3°. A. What is the index of refraction of the substance?  B. What is its likely identity?

A ray of light enters a flat surface of a block of glass (n=1.52) that is surrounded by water (n=1.33). If the refractive angle is 24.4°, what would be the angle of reflection? Select one: a. 28.17° b. 15.77° c. 18.10° d. 21.19°
