If the speed of light were the same in air and water, then the pencil would appear
straight, NOT broken. The beginning of the simplest explanation of why it does
appear broken is the fact that the speed of light is different in air and in water,
and that causes light to bend when goes from one into the other.
Yoiu can explain that observation with the difference of the speed of light in air and in water. But in fact, the speed is FASTER in air and SLOWER in water.
bends as it passes from air into water, causing the pencil to appear broken. This phenomenon is known as refraction.
refraction
This optical illusion is caused by light refraction at the boundary between the air and water. When light passes from air to water, it changes direction due to the change in media, making the pencil appear broken or disjointed at the water's surface.
When light passes from air to water, its speed changes, causing it to bend or refract. This refraction at the boundary of air and water causes the light rays coming from the pencil to change direction, creating an optical illusion that makes the pencil appear broken at the boundary. This phenomenon is known as refraction and is a result of the change in the speed of light as it moves from one medium to another with a different optical density.
This phenomenon, known as refraction, occurs when light travels through different mediums with varying densities, causing it to change direction. When a pencil is placed in water, for example, the light rays from the pencil bend as they pass from the air into the water, creating the illusion of a broken pencil.
-the pencil looks broken & bent in water. - the pencil looks bent, because of the refraction of light, that causes that to happen. -pencil looks really thick, in water.
A pencil is thing that you use to write stuff that you like! I hope it helps:)
Nothing happens when the ray of light hits the pencil. But it bends when it crosses the boundary between the air and the water. Your brain ... thinking that the end of the pencil is in the same direction that the ray of light is coming from ... thinks that the part of the pencil under the water is in a place where it's not, so the pencil appears bent at the water line.
First, remove broken pieces slowly. Then obtain new pencil and try to relax this time.
The pronoun for "my pencil" in the sentence "my pencil is broken" would be "it." In this case, "it" is a singular pronoun that replaces the noun "pencil" to avoid repetition in the sentence. Pronouns like "it" help make sentences more concise and easier to read by referring back to a previously mentioned noun.
That is a very sharp response...Writing with a broken pencil is pointless...
