Understanding Light Reflection

What is the definition of reflection of light?

• The reflection of light is the scattering of light rays in different directions.

• The reflection of light is the bouncing back of light rays when they hit a surface.

• The reflection of light is the absorption of light rays by a surface.

• The reflection of light is the conversion of light rays into heat energy.

What happens to light when it hits a mirror?

• Light is absorbed by the mirror completely.

• Light passes through the mirror without any change.

• Light reflects off the surface of a mirror.

• Light bends and changes direction when hitting the mirror.

What type of mirror is discussed in the video?

• Concave mirror

• Spherical mirror

• Flat mirror

• Convex mirror

How is a plane mirror different from other mirrors?

• A plane mirror only reflects light in one direction.

• A plane mirror is always curved unlike other mirrors.

• A plane mirror produces a clear, undistorted reflection, while other mirrors can distort images or focus light.

• A plane mirror can magnify images like a concave mirror.

What materials are used to make a mirror?

• Glass and a reflective coating (usually silver or aluminum)

• Paper and paint

• Wood and fabric

• Plastic and glass beads

What is the role of the silver layer in a mirror?

• The silver layer provides insulation to the mirror.

• The silver layer reflects light to create an image.

• The silver layer changes the color of the reflected image.

• The silver layer absorbs light to enhance brightness.

Can all objects reflect light?

• No, not all objects can reflect light.

• Yes, all objects can reflect light.

• All objects reflect light equally well.

• Only transparent objects can reflect light.

What are the two types of reflection mentioned?

• specular reflection, diffuse reflection

• partial reflection

• total internal reflection

• reflective scattering

What is regular reflection?

• Regular reflection occurs only on rough surfaces.

• Regular reflection is the reflection of light from a smooth surface where the angle of incidence equals the angle of reflection.

• Regular reflection happens at any angle of incidence.

• Regular reflection is when light is absorbed by a surface.

What is scattered reflection?

• Scattered reflection is the reflection of light from a smooth surface.

• Scattered reflection is the reflection of light from a rough surface in multiple directions.

• Scattered reflection is the bending of light as it passes through a medium.

• Scattered reflection refers to the absorption of light by a surface.
