To Choose: The correct option.
Answer to Problem 4STP
The correct option is (D).
Explanation of Solution
Introduction:
When light travels from air into water, it changes its direction slowly and this change in direction is called refraction of light. When light enters from a rarer medium to a denser medium, then it slightly bends towards the normal.
Refraction is the bending of light as light travels from one substance or medium into another. Refraction also occurs in sound waves. Refraction occurs when light goes into water surface since refractive index of water is more than air. When a pencil is placed in a bottle of water, partially immersed then the object appears to bend at the water’s surface. This bending of light is called refraction.
Conclusion:
Hence, the correct answer is (D).
