Question

a transparent medium x has refractive index of 1.4 and another transparent medium y has refractive index of 1.8. in which medium the ray of light bend more? how does the speed of light change when it goes from x to y ​

Answer 1

Answer:

in medium y the ray of light bend more because degree of bendness is directly proportional to refractive index of medium. speed of light decreases when it goes from medium X to Y

Answer 2

The ray of light bends more in y medium and speed of light decreases as it goes from x to y.

• Refractive index is defined as how fast the light travels in a medium and is given by speed of light in vaccum divided by speed of light in medium.
• So increase in the refractive index means decrease in speed of light in medium.
• Hence, the speed of light decreases from x to y
• The ray of light bends more in a medium with a higher refractive index.
• Hence, the ray bends more in y than x.
