Light Reflection and Properties

The video tutorial explains the concept of light reflection on smooth surfaces like mirrors. It defines key terms such as incident and reflected rays, point of incidence, and normal. The laws of reflection are discussed, emphasizing that the angle of incidence equals the angle of reflection. An experiment is demonstrated to show how mirrors change the direction of light, confirming that light travels in a straight path and does not bend.

What is the term used to describe the bouncing of light by a smooth surface?

• Reflection

• Absorption

• Diffusion

• Refraction

What do we call the light ray that falls on a mirror?

• Refracted ray

• Normal ray

• Incident ray

• Reflected ray

What is the name of the point where the incident ray strikes the reflecting surface?

• Point of reflection

• Point of refraction

• Point of incidence

• Point of diffusion

What is the line drawn perpendicular to the mirror at the point of incidence called?

• Incident line

• Reflected line

• Perpendicular line

• Normal

According to the laws of reflection, which of the following is true?

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

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

• The angle of incidence is less than the angle of reflection

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

In the experiment, what is used as the source of light?

• A flashlight

• A laser pointer

• A candle

• A torch

What should you do to see a patch of light on the other side during the experiment?

• Turn off the lights

• Adjust the torch

• Move to another corner

• Adjust the mirror

What conclusion can be drawn from the experiment?

• A mirror absorbs light

• A mirror diffuses light

• A mirror bends light

• A mirror changes the direction of light

What is the nature of the path of light?

• Random
