Reflection and Refraction

Part 1 – Reflection

DATA TABLE:

 Incident angle, θi 30 45 60 Reflected angle, θr

1. What can you conclude about the relationship of θi and θr? Does this verify the law of reflection?

Part 2 – Reflection:

Step I – Find the image location, circle that point and label it “I”. Measure and record the object distance do and the image distance di. What can you say about the location of the image?

Step J – Is the image real or virtual?

Part 3 – Refraction and the Refractive Index of Water:

Data Table

 Experiment Incident angle, θi Refracted angle, θr Index of refraction, n 1 2 3

Average value of the index of refraction, navg = _______________________.

Find the percent difference between the known value and your average experimental value.

Part 4 – Refraction and Refractive Index:

Data Table

 Experiment Incident angle, θi Refracted angle, θr Index of refraction, n 1 2 3

Average value of the index of refraction, navg = _______________________.

Find the percent difference between the known value of 1.49 and your average experimental value.
