Simple.... Refraction. Look it up ^_^
The bending of the straw in a glass of water is due to refraction of light. When light passes from air into water, it changes speed and direction, causing the apparent bending of the straw. This phenomenon is called refraction.
adhesion
Get a clear glass and half fill it with water. Place a straw or stick in the glass and if you look form the side you will see that where the stick enters the water it appear to have a kink in it. This is because the path of light is bent (refracted) by the water. When you stand in water and look down at your legs, this bending of the light make the image of your legs took foreshortened.
Water will bend a beam of light. Try this put a stright pincil in a glass of water. The pencil is still stright but looks bent. The water is bending the beam of light.
This is called adherence. It is the force of attraction between the water molecules and the glass molecules.
Refraction can best explain the apparent bending of a pencil when it is dipped into a glass of water. Refraction is the bending of light waves as they pass from one medium to another with a different density, such as air to water, causing objects to appear shifted or bent.
Cohesion .
Refraction of light can best explain the apparent bending of a pencil when it is dipped in a glass of water. This is due to the change in speed of light as it passes from air into water, causing the light rays to bend.
Refraction is the bending of light as it passes from one medium to another, such as from air into water or glass. This bending occurs due to the change in speed of light when it enters a new medium, causing the light to change direction. Refraction is responsible for phenomena like the apparent bending of a straw in a glass of water.
When a long stick is placed in a glass half-filled with water, the top view shows the stick appearing straight, while the side view reveals that the stick looks bent at the water's surface due to refraction. This bending occurs because light travels at different speeds in air and water, causing the light rays to change direction as they pass through the interface. In the drawing, the top view should depict the stick as a straight line, while the side view illustrates the stick appearing distorted at the water's surface. Descriptions should highlight the effect of refraction and the visual discrepancy between the two views.
Yes, light bends when it enters a glass of water due to the change in speed as it moves from air into water, causing it to refract. This bending of light is known as refraction.
go to your kitchen. open the cabinet in your kitchen. take a glass out of the cabinet in your kitchen. fill the glass that you got out of the cabinet in your kitchen with water. put sugar in the water that you put in the glass that you got out of the cabinet in the kitchen. put a stick in the sugar water that you put in the glass that you got out of a cabinet in the kitchen. wait till mornin or sometime later for the sugar in the water that you put in the glass that you got out of the cabinet in the kitchen to stick to the stick that you put in the sugary water in the glass from the cabinet on the kitchen. enjoy the confusement now c;
