What is the refractive index of benzene if the critical angle is 42 degrees?

What is the refractive index of benzene if the critical angle is 42 degrees?

According to Snell’s Law, C=sin −1 ( μ1 )⟹42 ∘ =sin −1 ( μ1 )⟹sin(42 ∘ ) μ= 0.671=1.49is the required refractive index of benzene.

When the angle of incidence in glass is 42 degree what will be the angle of refraction?

The corresponding angle of refraction is 90°.

What is the meaning of critical angle of a glass is 42?

The critical angle for ordinaryglass is 42 degree (approx) with respect to air. At a certain angle of incidence, known as the critical angle the refracted ray will be at 90° from the normal. No light is refracted. For glass at 42 degree no light get refracted.

What is the refractive index of material if its critical angle is 45 degree?

Here, C=45∘,μ=? μ=1sinC=1sin45∘=11/√2=√2.

What is the angle of refraction for critical angle?

90-degrees
When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle; it is the largest angle of incidence for which refraction can still occur.

What is the index of refraction of benzene?

What is critical angle for glass?

Light travels from glass to air. Angle of refraction is greater than angle of incidence. All light waves, which hit the surface beyond this critical angle, are effectively trapped. The critical angle for most glass is about 42°.

What is relation between critical angle and refractive index?

The ratio of velocities of a light ray in the air to the given medium is a refractive index. Thus, the relation between the critical angle and refractive index can be established as the Critical angle is inversely proportional to the refractive index.
