The curvature of the lens is the most important characteristic in bending light rays to form a focused image. The shape and thickness of the lens determine how light is refracted and focused to create a sharp image.
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.
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 light travels from air into glass, it may not bend if it hits the glass surface perpendicular to it, which is called normal incidence. In this case, the speed of light doesn't change as it enters the glass, so there is no bending of the light ray. However, if the light hits the glass at an angle, it will bend due to the change in speed between air and glass, a phenomenon known as refraction.
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.

glass can produce a refraction (bending) of light
glass can produce a refraction (bending) of light
Glass bending procedure without dents
Process of glass bending Bending of glass is a physical process. Glass having high melting point can de bend to desiered shape these are known as borosil glasses,constant heat along with pressure in desiered direction is applied .pressure should be lower then the effect and temparature of heat other wise there are chances of breaking or cracking of glass
Unlike an optical lens, maximum 'bending' occurs closest to, and minimum 'bending' furthest from, the center of a gravitational lens.
Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
Simple.... Refraction. Look it up ^_^
Some glass is transparent to visible light.
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.
that depends. changing the shape of glass is physical but if its a glass that can be effected by heat then if can be chemical. i would say its both.
TUBES going left to right: Attach a down and right bending tube on #1 (first column) Do not attach anything to #3 (second column) Attach a right bending, then down bending, then right bending tube on #3 (third column) Attach a right bending tube on #1 (fourth column) Attach a right bending tube on #2 (fifth column) Attach a left bending, then straight tube on #2 (sixth column) Do not attach anything to #3 (seventh column). GLASSES Place a vertical 3 glass directly under the #3 tube in the second column. Place the horizontal 3 glass directly on top of horizontal 4 glass stretching from 2nd-4th column. (leaving only one space open on the 4 glass in the fifth column) Place the vertical 2 glass directly next to the 4 glass in the sixth column. Place the vertical 3 glass directly next to the 2 glass in the seventh column.
Because if you didn't the glass beaks MUCH easier, and will injure you.
