To determine the index of refraction of acryl from
the apparent depth.
First. you are looking purpose. In this experiment, the purpose is to measure the apparent depth of acryl.
And then, To determine the index of refraction of acryl from the apparent depth.
In this slide, I am going to explain the apparent depth.
For a transparent block, Light rays originating from the bottom surface refract at the top surface as the rays emerge from this inner point.
d is the apparent depth. t is actual thickness of the block.
The apparent depth is theoretically defined by d = t/n(t over n), where n is the index of refraction of the material.
If d is measured experimentally, n can be determined by t over d
