Which of the following statements is correct?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → If the reflecting surface is smooth, the reflection is regular.
On a smooth, polished surface such as a plane mirror, parallel rays of light are reflected as parallel rays; this is regular reflection, and it forms clear images. On a rough surface such as cardboard, the rays go off in different directions; this is diffused or irregular reflection. The laws of reflection hold in both cases.
