Physics Lab: Reflection and Refraction of Light Rays Lab Pre-lab Exercise The device in Activity 1 and 2 is shown in the figure on the right. The protractor has two sets of readings for each angle. We will use the readings on the INNER circle as highlighted by the dark circle (in RED). The marks on the left and right sides of this INNER circle are 0 degree, and The marks on the top and bottom sides of this INNER circle are 90 degree. The figure on the left shows the geometry used in refraction of light rays the desired angles of INCIDENCE are given. Find the corresponding INNER readings on the protractor. some hypothetical INNER readings of the REFRACTED. rays are given. Find the angles of REFRACTION for these hypothetical REFRACTED rays.Explanation / Answer
for Given Set up :
angle reading from protractor = 90 - incident angle
0 -> 90
15 -> 75
30 -> 60
45 -> 45
60 -> 30
75 -> 15
same goes fro refacted angle.
0 > 90 deg
15 - > 75
30 -> 60
45 -> 45
60 -> 30
75 -> 15
