Understanding Light Reflection

What is the phenomenon of light bouncing off a surface called?

• Reflection

• Diffraction

• Refraction

• Absorption

What is the first law of reflection?

• The angle of incidence is always greater than the angle of reflection.

• The angle of incidence is half the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence and reflection are both 90 degrees.

According to the second law of reflection, what do the incident light ray, reflected light ray, and normal line have in common?

• They all have different angles of incidence.

• They all originate from the same source.

• They all lie in the same plane.

• They all travel at the same speed.

What happens to a light ray that strikes a reflecting surface perpendicularly?

• The light ray splits into multiple rays upon striking the surface.

• The light ray reflects back along the same path.

• The light ray passes through the surface without reflection.

• The light ray bends away from the surface.

What are the two main types of mirrors?

• Reflective and non-reflective mirrors

• Opaque and transparent mirrors

• Concave and convex mirrors

• Flat mirrors and curved mirrors

What type of mirror is a concave mirror?

• A concave mirror is a type of cylindrical mirror that is curved outward.

• A concave mirror is a type of plane mirror that has no curvature.

• A concave mirror is flat and reflects light outward.

• A concave mirror is a type of spherical mirror that is curved inward.

What is the main characteristic of a plane mirror?

• It produces a real image that is not inverted.

• It reflects light in multiple directions.

• The main characteristic of a plane mirror is that it produces a virtual image that is laterally inverted.

• It creates a colored image that is distorted.

How does the angle of incidence relate to the angle of reflection?

• The angle of incidence and reflection are unrelated.

• The angle of incidence is always greater than the angle of reflection.

• The angle of incidence is half of the angle of reflection.

• The angle of incidence equals the angle of reflection.

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

• The normal line is a visual aid for drawing reflections.

• The normal line helps determine the angles of incidence and reflection in the reflection process.

• The normal line is used to measure the speed of light.

• The normal line indicates the direction of sound waves.

What type of mirror is a convex mirror?

• A convex mirror is a flat mirror.

• A convex mirror is a converging mirror.

• A convex mirror is a diverging mirror.

• A convex mirror is a reflective lens.
