Snell’s Law Practice Worksheet: Snell’s Law Practice Worksheet Answers
Introduction
This worksheet provides practice problems and examples to help students understand and apply Snell’s law, a fundamental principle in optics.
Snell’s law describes the relationship between the angles of incidence and refraction when light passes from one medium to another. It is given by the equation:
n1sin θ 1= n 2sin θ 2
where n 1and n 2are the indices of refraction of the two media and θ 1and θ 2are the angles of incidence and refraction, respectively.
Worksheet Overview
This worksheet is divided into the following sections:
- Example Problems: Provides solved examples to demonstrate the application of Snell’s law.
- Practice Questions: Presents a table of questions covering various aspects of Snell’s law.
- Answer Key: Contains the correct answers to the practice questions with explanations.
Example Problems, Snell’s law practice worksheet answers
Problem 1:Light travels from air (n 1= 1) to glass (n 2= 1.5). The angle of incidence is 30 degrees. What is the angle of refraction?
Solution:
- Substitute the given values into Snell’s law:
- Solve for θ 2:
1 sin 30° = 1.5 sin θ2
θ 2= sin -1(1 sin 30°/1.5) ≈ 19.5°
