Reflection Principles and Mirror Types

The video tutorial discusses the types of mirrors, including plane and spherical mirrors, and the laws of reflection. It explains the characteristics of plane mirrors and the classification of spherical mirrors into convex and concave types. The tutorial also covers the laws of reflection, emphasizing the angle of incidence and reflection, and introduces Fermat's principle and wave optics concepts.

What are the two main types of mirrors discussed in the video?

• Convex and concave mirrors

• Reflective and non-reflective mirrors

• Plane and spherical mirrors

• Plane and cylindrical mirrors

What is a characteristic of a plane mirror?

• It is always concave

• It has no curvature

• It is painted on the reflecting side

• It is curved

How is a spherical mirror created?

• By painting a flat surface

• By using a concave lens

• By cutting a hollow glass sphere

• By bending a plane mirror

What is another name for a convex mirror?

• Reflective mirror

• Diverging mirror

• Converging mirror

• Plane mirror

According to the first law of reflection, what is true about the angles of incidence and reflection?

• They are complementary

• They are supplementary

• They are equal

• They are always different

What principle explains why the angle of incidence equals the angle of reflection?

• Huygens' principle

• Fermat's principle

• Newton's principle

• Snell's principle

What does the second law of reflection state about the incident ray, reflected ray, and normal?

• They are parallel

• They lie in different planes

• They lie in the same plane

• They are perpendicular

What is the role of the normal in the reflection process?

• It is parallel to the mirror

• It is perpendicular to the mirror at the point of incidence

• It is the path of the incident ray

• It is the path of the reflected ray

What happens to light when it travels from point A to point B via reflection?

• It takes the longest path

• It does not reflect

• It takes the shortest path

• It takes a random path

What is the significance of the plane in the second law of reflection?

• It determines the speed of light

• It ensures the rays are parallel

• It ensures the rays and normal lie in the same plane

• It reflects light at different angles
