Light Reflection

What do you call the phenomenon by which the incident light falling on the surface is sent back into the same medium?

• Absorption

• Reflection

• Polarization

• Refraction

What angle is formed by an incoming ray and the normal line?

• Angle of reflection

• Angle of refraction

• Angle of incidence

• Angle of equivalence

Which statement correctly describes the “Law of reflection”?

• The angle of reflection is perpendicular to the normal.

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

• The angle of reflection is parallel to the angle of incidence

• Both the angle of incidence and reflection lie in different planes.

What type of reflection is produced by rough surfaces?

• Diffuse reflection

• Dispersion

• Specular reflection

• Total internal reflection

Which of the following best describes a Normal line?

• The path is taken by the rays of light as it approaches the surface

• Line parallel to the incident and reflected ray

• The total distance traveled by light upon reflecting

• An imaginary line is drawn perpendicular to the reflecting surface

Which of the following pairs perfectly describe the reflection produced by a smooth surface?

• Diffuse reflection: clear and precise

• Specular reflection: clear and precise

• Diffuse reflection: not clear and vague

• Specular reflection: not clear and vague
