Question
Why does the straw appear disconnected when partially submerged in water?
• Refraction causes the light from the lower part of the straw to bend as it moves from water to air, creating the illusion of separation
• The light from the entire straw travels in a straight line to your eye
• The upper part of the straw emits its own light, causing the illusion
• The light reflecting off the straw is blocked by the water, making it hard to see
• Refraction causes the light from the lower part of the straw to bend as it moves from water to air, creating the illusion of separation

The correct explanation for why the straw appears disconnected when partially submerged in water is:
**Refraction causes the light from the lower part of the straw to bend as it moves from water to air, creating the illusion of separation.**
When light passes from one medium (water) to another (air), it changes speed and direction, a phenomenon known as refraction. As a result, the light from the submerged part of the straw is bent at the water-air interface, leading to the visual illusion that the straw is broken or separated at the surface of the water.
