Light Interaction and Reflection Concepts

The video tutorial explains how light interacts with surfaces through reflection, absorption, and transmission. It distinguishes between diffuse reflection on rough surfaces and specular reflection on smooth surfaces, using analogies like cricket to illustrate concepts. The tutorial also covers symmetry in reflection and how light can be absorbed or transmitted through materials.

What analogy is used to describe the interaction of light with surfaces?

• A cricket ball hitting a bat

• A car driving on a road

• A bird flying in the sky

• A fish swimming in water

What happens to light when it hits a rough surface?

• It is absorbed completely

• It passes through the surface

• It is reflected in a single direction

• It is scattered in various directions

Which type of reflection occurs on smooth surfaces like mirrors?

• Absorptive reflection

• Scattered reflection

• Diffuse reflection

• Regular reflection

What is a key characteristic of regular reflection?

• Light is reflected predictably

• Light passes through

• Light is absorbed

• Light is scattered

What does symmetry in reflection mean?

• Light is scattered symmetrically

• Light is absorbed equally

• Light passes through symmetrically

• Both sides of a mirror reflect light equally

In a vacuum, how does light interact with objects?

• It is transmitted

• It does not interact

• It is absorbed

• It is reflected

What happens during absorption of light?

• Light is reflected

• Light is scattered

• Light is absorbed by the object

• Light passes through the object

What is transmission in terms of light interaction?

• Light is scattered

• Light is absorbed

• Light is reflected

• Light passes through an object

What type of materials allow light to pass through them?

• Absorptive materials

• Transparent materials

• Reflective materials

• Opaque materials

What is an example of a transparent object?

• A stone wall

• A metal sheet

• A glass window

• A wooden door
