# Why does the straw appear to be broken?

## Why does the straw appear to be broken?

But below, when the light also travels through water, the refraction causes the image of the straw to be in a slightly different location. The water also acts as a type of magnifying lens, making the size of the straw seem larger than it actually is. To the brain, the straw appears broken (and bloated).

Why do objects look broken underwater?

As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes medium and subsequently undergoes refraction. As a result, the image of the pencil appears to be broken. At the boundary, this ray refracts.

### Does water refract or reflect light?

Water and glass not only reflect but also refract light. This means that as a light beam enters water or glass, the light bends.

What behavior causes these straws to appear broken at the water line?

A: The straw appears to be broken because of refraction. Light slows down and bends when it passes from the water in the glass to the air on its way to your eyes.

## Why does a stick partially immersed in water appears bent broken?

When stick is immersed partly in water then light coming from stick refracts at the surface of water due to change in density of medium. Because water and air hasdifferent refractive index. When stick is dipped in water the angle of refraction changed thats why it seemed to be bent.

Why straw in a glass filled with water appears bent?

Refraction is the bending of light as it passes from one medium into another (ie. air to water, water to air). As you look at the straw in the glass of water, the light coming from the straw to your eye bends as it passes through three different mediums (water, glass, and air).

### Why do objects at the bottom of an aquarium filled with water look closer than they really are?

An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. This tutorial explores how fish, observed from the bank of a pond or lake, appear to be closer to the surface than they really are.
