Question

Be sure that you measure all angles with respect to line on whichever side of the he the light ray is.

Question: Based on your observations, qualitatively describe how the angle of refraction compares to the angle of incidence for each trial? 3. Reverse the position of the lens so that the flat side of the lens is again lined along the "component line" of the ray table, only now, the incoming beam initially strikes the curved side of the lens as shown in Fig. 2 on the next page. 221

Answer 1

Q1) qualitatively from the table 4.1 we see that the angle of reflection is exactly equal to the angle of incidence.

Q2) the angle of refraction is smaller compare to the angle of incidence.

Part 4 : table 4.2

Q 1) from table 4.2 we see that the angle of refraction is more than the angle of incidence.
