Question

a ray of light is incident on a medium with angle of incidence i and is refracted into a second medium with angle of refraction r the graph of sini versus sinr is shown. find the ratio of the velocity of light in the first medium to the velocity of light in second medium

Answer 1

Answer:

The angle that the incident ray creates with the refracted ray is generated at the point of refraction, not to mention the normal line that is dropped on the plane perpendicularly. In contrast to reflection, the medium through which light rays flow makes a significant variation in refraction. In Snell's Law, the refractive indices reveal the medium's dependence.

Explanation:

1. The refracted ray's angles at the contact point are measured using the normal on the surface. The two distinct media that will influence refraction are n1 and n2.
2. Water has a refractive index of 1.33, while air has a refractive index of 1.00029. Consider the light of wavelength 600 nm that passes through water and into the air to better comprehend Snell's Law. We use the values in the formula above to compute the angle created by the outgoing beam.
3. 1.00029 sin x x = 41o = 1.33 sin 30o

Form Snell's law,

μ1sini=μ2sinr⇒μ2μ1=sini/sinr

Form the graph,

tan60∘=sini/sinr⇒sini/sinr=3–√=μ2μ1

μ=cv⇒=μ1μ2=v2v1

v1=(μ2μ1)v2⇒v1=3–√v
