2. What value did you calculate for the index of refraction of the block in Part 2? How does your value compare to the accepted value of 1.50? Calculate the percentage error.
To calculate the value for the index of refraction of the block in Part 2, you first need to determine the angle of incidence and angle of refraction.
1. Measure the angle of incidence: Use a protractor to measure the angle at which the beam of light enters the block.
2. Measure the angle of refraction: Similarly, use a protractor to measure the angle at which the beam of light exits the block.
Once you have obtained these two values, you can calculate the index of refraction using Snell's Law:
n = sin(θ₁) / sin(θ₂)
where:
- n is the index of refraction
- θ₁ is the angle of incidence
- θ₂ is the angle of refraction
Now, to compare your calculated value to the accepted value of 1.50, subtract the accepted value from your calculated value and divide the result by the accepted value. Finally, multiply the obtained value by 100 to get the percentage error:
Percentage Error = [(Calculated Value - Accepted Value) / Accepted Value] * 100
By following these steps, you can determine the value you calculated for the index of refraction of the block in Part 2 and calculate the percentage error.
