The angle of incidence is greater than the angle of refraction. What about the speed of light in the second medium?
| February 18, 2021 | education
The law of refraction of light at the interface between two media can be written as:
sin a / sin b = V1 / V2,
where a is the angle of incidence, b is the angle of refraction, V1 is the speed of light in the first medium, V2 is the speed of light in the second medium.
If a> b, then in the interval 0 ° <a <90 ° the inequality sin a> sin b and sin a / sin b> 1 is valid.
Then V1 / V2> 1 and V1> V2.
Answer: the speed of light in the second medium is less than the speed of light in the first medium.
