Light Reflection and Angles

The video tutorial explains the concept of curvature and its role in reflection. It covers the principles of reflection through the center of curvature, the effects of normal incidence, and the implications of zero-degree reflection. The session concludes with a summary of the key points discussed.

What happens to a light ray passing through the center of curvature after reflection?

• It forms a new angle with the mirror.

• It retraces its path.

• It converges at a point.

• It diverges away from the mirror.

Why does a light ray passing through the center of curvature retrace its path after reflection?

• Because it is tangent to the mirror.

• Because it is parallel to the mirror.

• Because it is perpendicular to the mirror.

• Because it hits the mirror at an angle.

What is the significance of the normal line in reflection?

• It is the line that bisects the angle of incidence.

• It is the line perpendicular to the mirror.

• It is the line parallel to the mirror.

• It is the line at an angle to the mirror.

What is the angle of incidence when light hits the mirror normally?

• 180 degrees

• 45 degrees

• 0 degrees

• 90 degrees

What is the angle of reflection when light hits the mirror normally?

• 90 degrees

• 0 degrees

• 45 degrees

• 180 degrees

What is the relationship between the angle of incidence and the angle of reflection?

• They are equal.

• They are complementary.

• They are supplementary.

• They are unrelated.

What happens to the light ray if it is incident at 90 degrees to the mirror?

• It forms a new angle.

• It gets refracted.

• It gets absorbed.

• It retraces its path.

What is the angle of incidence if the angle of reflection is 0 degrees?

• 45 degrees

• 180 degrees

• 0 degrees

• 90 degrees

What is the behavior of light when it is incident normally on a mirror?

• It gets refracted.

• It gets absorbed.

• It forms a new angle.

What is the angle of reflection if the angle of incidence is 0 degrees?

• 45 degrees

• 90 degrees

• 180 degrees

• 0 degrees
