A light beam in air (Dair =1.0003) has an angle of incidence of 35° at the surface of a glass plate (nalass =1.5). What are the angles of reflection and refraction?

Final answer:

The angle of reflection is 35° and the angle of refraction is approximately 22.98°.

Step-by-step explanation:

The angle of reflection can be found using the law of reflection, which states that the angle of reflection is equal to the angle of incidence. Therefore, the angle of reflection is also 35°.

To find the angle of refraction, we can use Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the indices of refraction.

In this case, the angle of incidence is 35° and the index of refraction of air is 1.0003, while the index of refraction of glass is 1.5. Plugging these values into Snell's Law, we can find the angle of refraction.

sin(35°) / sin(Angle of refraction) = 1.0003 / 1.5

Solving for the angle of refraction, we find that it is approximately 22.98°.
