Question

what conclusion can be drawn about reflected angles and incident angles from the table

Incident Ray Angle of Incidence, Oj C, measured from Normal) 20 Angle of Reflection, O. C, measured from Normal) 19 A B 42 43 С 70 69 Table 1

Answer 1

Case A )

Incident angle = 20 degree

Reflected angle = 19

Case B)

Incident angle = 42°

Reflected angle = 43°

Case C)

Incident angle = 70°

Reflected angle = 69°

From the above three sets of readings , we can conclude that the angle of incidence is almost equal to the angle of reflection.

Conclusion: angle of incidence= angle of reflection
