## Why does my straw look bent in water?

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).

## Why do things look bent in water?

Refraction occurs when light goes through a water surface since water has a refractive index of 1.33 and air has a refractive index of about 1. Looking at a straight object, such as a pencil in the figure here, which is placed at a slant, partially in the water, the object appears to bend at the water’s surface.

## Which term best describes why a straw in a glass of water appears 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.

## When the pencil is kept in a glass of water it seems to be broken Why?

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.

## When a pencil kept in a glass tumbler filled with water seen from the side of the glass it seems to bend due to?

The pencil appears to be bent when it is kept in a glass tumbler with water due to refraction of light. The refraction of light occurs when the speed of light changes when it travels from one medium to another.

## Why does the pencil appear bent?

Because the light can’t travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water. Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.

## Does a pencil appear to be displaced to the same extent?

The refraction of light occurs because the speed of light changes when light travels from one medium to another. Therefore, the pencil will not appear to be bent to the same extent, when it is dipped in kerosene or turpentine.

## When partly immersed in turpentine oil the pencil appears displaced as shown in the following figure give reason?

The refraction of light occurs because the speed of light changes when it goes from one medium to another. Therefore,the pencil will not appear to bend to the same extent when it is dipped in kerosene or turpentine.

## Why does a stick immersed obliquely in water appears bent and short?

(a) The apparent bending of the stick is due to the refraction of light when it passes from water into air. A ray of light OC coming from O passes from water into air and gets refracted away from normal (along CX). Another ray OD gets refracted along DY.

## How a lemon appears when it is kept in water of glass?

Since the lemon is kept in the glass and light rays move from water to air that is from denser medium to a rarer medium, they move away from the normal and due to this refraction phenomenon, the lemon appears larger to the observer.

## What does the N stand for in Snell’s law?

Like with reflection, refraction also involves the angles that the incident ray and the refracted ray make with the normal to the surface at the point of refraction. The constants n are the indices of refraction for the corresponding media. …
