What is an example of refraction in daily life?

• A. A rainbow forming in the sky
• B. A straw appearing bent in a glass of water
• C. Sound traveling faster in air than in water
• D. The distortion of an image in a curved mirror

Answer: (B)

Refraction occurs when light passes from one medium to another at an angle, causing it to change speed and direction. The bending of a straw when it is placed in a glass of water is a classic example of refraction in daily life. As light moves from air (a less dense medium) into water (a denser medium), it slows down and bends. This bending makes the straw appear as if it is bent at the surface of the water, even though it is straight. This phenomenon highlights how changes in the medium through which light travels can alter our perception of objects. The other choices, while related to various optical or physical phenomena, do not depict refraction. A rainbow forms through both refraction and reflection of light in water droplets, sound traveling through different mediums involves wave propagation principles but is not directly related to light refraction, and the distortion of an image in a curved mirror is due to reflection rather than refraction.
