Question

The image shows a ray of light bending at the boundary of a glass block. According to a law of optics, = n, where n is a constant. Which equation states the same law in terms of a and b?

Answer 1

The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a

Answer 2

Answer:

its C

Step-by-step explanation:

i is the cosin of a qne r is the cosin of b so its the same
