Question
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 degrees, and The marks on the top and bottom sides of this INNER circle are 90 degrees.
Normal to the interface Incident Ray from ray box The figure on the left shows the geometry used in refraction of light rays Normal to the interface Medium 1, nI HEL SA Medium 2, 1 02 efracted ray 90° : Hypothetical Refracted ray Table 1 the desired angles of INCIDENCE are given. Find the corresponding INNER readings on the protractor Table 2 some hypothetical INNER readings of the REFRACTED rays are given. Find the angles of REFRACTION for these hypothetical REFRACTED rays.Explanation / Answer
For angle of incidence - inner reading on protractor
0 - 270
15 - 255
30 - 240
45 - 225
60 - 210
75 - 195
For refracted rays - inner reading on protractor
0 - 90
15 - 75
30 - 60
45 - 45
60 - 30
75 - 15
