Question

In following. Diamond, alcohol, crown glass, water which is the material medium a ray of light bends the least

Answer 1

Answer:

answer is diamond

Explanation:

The highest refractive index is of Diamond with its value 2.42.

Refractive index of glass is 1.5.

Refractive index of water is 1.33.

Refractive index of ruby is 1.77.

Answer 2

THE RAYS OF LIGHT WILL BEND THE LEAST IN WATER.

Explanation:

• The refractive index is the ratio of the velocity of light in air to the velocity of light in a medium.
• The rarer the medium will be, the least the bending towards normal will be.
• Whereas in denser medium, the bending of light towards the normal is maximum.
• The value of refractive index are:

         Water = 1.33

         Alcohol = 1.36

         Crown glass = 1.52

         Diamond = 2.42

• The refractive index in increasing order is Water > Alcohol > Crown glass > Diamond.
• Therefore, in water light will bend the least.
