chapter:- refraction of light​

Answer 1

Answer:

Refrection of light

Explanation:

your reasons solve your physices teacher

Answer 2

It looks like a sack that is enclosed with a drawstring, because of refraction.

• Refraction is the bending of light rays when it passes from one medium to another.
• A body emerging in water looks thicker and larger in water than in air because it obeys Snell's law.
• Snell's can be written as

Snell's can be written as n1θ1=n2θ2.

• Because the air has an index of refraction of 1 and water has an index of refraction of 1.33.
• In water, the angle by which the rays of light strike your eyes is larger than the angle it forms in air.
• This makes the angular size larger and it makes the object look larger in water than it would look in air.
