Answer

To verify the laws of reflection, we can follow these steps in sequential order:

1. **Step D**: Draw a straight line on a white paper spread on the table and fix a plane mirror on the line.
- This serves as the baseline for our experiment and where we will place the mirror.

2. **Step E**: Fix two pins P and Q in front of the mirror.
- These pins will help us visualize the incident rays of light.

3. **Step C**: View the image of P and Q and fix two more pins P1 and Q1 such that the images of pins P, Q and P1, Q1 are along the same line.
- This step ensures that we can see the reflection of the pins clearly and align them properly.

4. **Step A**: Draw a normal at the point where the two lines PQ and P1Q1 meet.
- The normal line is essential for measuring the angles of incidence and reflection.

5. **Step B**: Remove the pins and the mirror and join P, Q; similarly join P1, Q1.
- This step allows us to visualize the paths of the incident and reflected rays without the obstruction of the pins.

6. **Step F**: Measure the angle of incidence and angle of reflection and compare them to verify the law of reflection.
- This final step confirms whether the angles are equal, thus verifying the law of reflection.
