# What happens when a straw look bent in water?

## What happens when a straw look bent in water?

Above the water, the light reflects from the straw through the air and glass to your eyes. But below, when the light also travels through water, the refraction causes the image of the straw to be in a slightly different location. To the brain, the straw appears broken (and bloated).

What happen when you bent a straw?

Answer. Answer: Refraction is the bending of light as it passes from one medium into another (ie. 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).

When a straw appears broken in a glass What has happened?

Light bends when it passes from one medium (air) into another medium of a different density (water). This bending of light, called refraction, causes the straw to look broken​1​.

### Which of these explains why a straw in a glass of water often appears bent or broken?

Refraction causes the straw to appear broken. Explanation: The reason for the straw to break at the water’s surface is because of the process of refraction. Light travels at different speeds in different medium because of the varying densities.

Why does a straw in a clear cup of water seem broken bent when seen at an angle?

So as we look at the straw in the glass, the light from the top part of the straw travels straight to our eyes whereas the part of the straw that’s underwater has light that is refracted since it goes from air to water, back to air again, so the light travels to the eye at a slightly different angle therefore making …

Why do you think the straw was bent?

#### What happened when you placed it in a glass with water?

Refraction is the bending of light. In this case, light traveled from the air, through the front of the glass jar, through the water, through the back of the glass jar, and then back through the air, before hitting the picture. Whenever light passes from one medium into another, it refracts.

Why does a pencil look bent in a glass of water?

In this experiment, light first travels through the air – which is easy to move through – and then through the water, where it slows down. This change in speed causes the light to bend, or refract, meaning that the part of the pencil that is in the water will appear shifted.

What happened to the fork when you pour water in a glass?

Answer: When we fill the glass with water, we notice right away that it can go over the brim of the glass without spilling. This is because of surface tension. This attraction causes the molecules to stick together and avoid spilling down the side of the glass like gravity would like them to.

## Why can you see the coin without changing your position?

Light bends when it passes from one medium (water) into another medium of a different density (air). This bending of light, called refraction, causes the apparent position of the coin to change to a shallower position​1​ (see diagram). As a result, you see two images of the coin.

What happens when you drink with a straw?

When you drink with a straw, makes you swallow air. The swallowing of air can cause stomach bloating, digestion issues and uncomfortable abdominal cramping. If you do not want the gastric problems then going straw free is the best solution. When you drink with a straw, you also swallow some amount of air with it.

Why does drinking from a straw stain your teeth?

Many people believe that in order to keep the teeth white and shiny, you should drink with a straw. But by using the straw you consume more than the usual quantity of drink.Therefore, if we drink a drink from the straw, it comes in contact with our teeth directly, it causes stains on the teeth.

### What happens when you put a straw in your mouth?

The term “smoker’s lips” refers to wrinkles around the mouth due to prolonged cigarette smoking. It can also happen due to repeated use of a straw, which involves a similar lip movement. When you place a straw in a drink, it captures some air. The air travels to your digestive tract, causing increased gas and bloating.

When did people start drinking beer through straws?

Humans have been using straws for thousands of years. The straw dates back to at least 3000 B.C., when Sumerians drank beer through tubes made of gold. In the 1800s, people used stalks of rye as straws. The paper straw was introduced in 1888, but by the 1970s, plastic straws became popular. Today, straws are widely used.
