true or false when we see a pencil in a glass of water,the pencil looks bent.?

Question

my answer is the pencil seems broken.

Answer 1

It is true because of the refraction of light waves. When any wave passes from one medium to other because of its density it bends. In the case of light also it appears to be bent. In case of sound and earthquake waves it really bents from its normal angle of propagation. The binocular uses this tech-knowledge by the use of prism to get complete reflection through refraction process to reduce the length. Otherwise the binocular also will look like telescope. Hope you understand. What you get from mirror is reflection.What you get from glass is refraction.

Answer 2

The pencil looks bent because of the different refraction indexes of air and water: this causes light to deviate from the starting direction (in the water) to another one (in the air) so we perceive the pencil as being broken

Answer 3

My answer is, looks like two different pencils. Not broken or bent.

Answer 4

Its called light refraction....Better question..........If you put the pencil directly in the center of said glass of water...will the pencil fall to the right or left..or just stand still?

Answer 5

When the pencil is totally immersed in water, it does not look bent from the outside. When partially immersed in water, it looks bent from outside and inside

Answer 6

True, Lead hasn't been in pencils for at least 40 or more years

Answer 7

True. Google "refraction"

Answer 8

Depends on the angle u look at it

Answer 9

that is true
that is due to rhe phenomenon called refraction

Answer 10

true
