Question

4. Given a material of index of 1.35 and

an angle of refraction of 15 degrees
what would the angle of incidence most
likely bein air where the index is 1?

Answer 1

The angle of incidence in air can be found using Snell's Law and the given angle of refraction and index of refraction.

Step-by-step explanation:

When light travels from one medium to another, it bends or refracts. The angle of incidence (i) and the angle of refraction (r) are related by Snell's Law:

n_1 * sin(i) = n_2 * sin(r)

Given an angle of refraction of 15 degrees and an index of refraction of 1.35, we can find the angle of incidence in air (where the index is 1) by rearranging and solving the equation.

Using the formula: sin(i) = (n_2 / n_1) * sin(r), we can substitute the values: sin(i) = (1 / 1.35) * sin(15). Solving this equation, the angle of incidence is approximately 10.29 degrees.
