When observing a spoon submerged in a glass of water, what optical phenomenon explains why the spoon appears bent?

• The spoon actually bends due to the water's properties.

• Light is absorbed by the water, distorting the image.

• Light is reflected off the water's surface, causing distortion.

• Light is refracted, or bent, as it passes from air into water.
