Question

A ray of light approaches a jar of honey at an angle of 25°. If the angle of refraction is 21.5°,what is the refractive index of honey".

Answer 1

Answer:

1.153

Step-by-step explanation:

ATQ,

i= 25°

r= 21.5°

Values from sines list (approx.),

sin(25°) = 0.423

sin(21.5°) = 0.367

Now, we know that,

η₁ sin i = η₂ sin r

=> η₂/η₁ = sin i/ sin r

=> ₁η₂= sin25°/sin21.5°

=> ₁η₂= 0.423/0.367

=> ₁η₂= 1.153 (approx.)
