Mirror Properties and Light Reflection

The video tutorial introduces the concept of light reflection, explaining how light travels in a straight line and can be redirected by polished surfaces like mirrors. It includes a hands-on experiment to demonstrate how light reflects off a mirror, forming images. The tutorial further explores the differences between smooth and rough surfaces in reflecting light, highlighting the clarity of images formed. It concludes with a guide on making a simple mirror using glass and silver plating.

What happens when light is obstructed by an opaque object?

• It bends around the object.

• It forms a shadow.

• It changes color.

• It speeds up.

What is the term for the change in direction of light when it hits a mirror?

• Absorption

• Reflection

• Diffusion

• Refraction

Which of the following surfaces can act like a mirror?

• A brick wall

• A piece of paper

• A clear water surface

• A rough wooden table

What is the main reason rough surfaces do not produce clear images?

• They absorb all the light.

• They are too shiny.

• They are transparent.

• They reflect light in multiple directions.

What is the term for reflection that occurs on rough surfaces?

• Diffused reflection

• Partial reflection

• Total internal reflection

• Specular reflection

Why do highly polished surfaces like mirrors produce clear images?

• They have larger bumps.

• They absorb more light.

• They are transparent.

• They reflect light at the same angle it hits them.

What is a simple mirror made of?

• A piece of wood with a shiny coating

• A plain glass with silver plating

• A plastic sheet with a reflective surface

• A metal plate with a smooth finish

What additional layer is used in mirrors to protect the silver coating?

• A layer of glass

• A layer of plastic

• A layer of red paint

• A layer of wax

How does the red paint on a mirror help?

• It prevents light from passing through.

• It absorbs excess light.

• It makes the mirror more reflective.

• It enhances the color of the reflection.

What is the primary function of the silver coating on a mirror?

• To make the mirror colorful

• To provide a smooth surface

• To absorb light

• To make the mirror shiny
