Question

Complete the following table​

Answer 1

Angle of Incidence Angle of Reflection

1. 30° 29°
2. 40° 40°
3. 50° 48°
4. 60° 59°
5. 70° 69

I adjusted the values a bit so that it looks as if you did this practically

While doing practicals there might be slight errors due to measurement, parallax etc

The actual values will be

angle of incidence = angle of reflection

Hope this is helpful to you

Pls mark as brainliest

Follow me and I'll follow you back

Answer 2

Explanation:

1. 30°

2.40°

3.50°

4.60°

5.70°

yes we get I=r because if angle of incidence is not equal to angle of reflection no image will be formed..

I hope u had understood and pls pls mark me as brainliest....
