Properties and Behavior of Light

The video tutorial explores the properties of light, focusing on reflection, refraction, and absorption. It explains how light reflects off smooth surfaces at equal angles of incidence and reflection, how rough surfaces diffuse light, and how refraction occurs when light passes through different substances. The tutorial also covers how light absorption affects the colors we perceive, using practical examples like photographing egrets and boats.

What was the initial challenge faced while trying to capture the white egret?

• The sunlight was reflecting into the camera lens.

• The tripod was broken.

• The camera battery was low.

• The egret was too far away.

What happens to light when it hits a smooth, shiny surface?

• It gets absorbed completely.

• It reflects at the same angle it hits.

• It bends and changes direction.

• It scatters in all directions.

What is the angle of incidence?

• The angle at which light is scattered.

• The angle at which light is absorbed.

• The angle at which light hits a surface.

• The angle at which light bends.

Why does the red boat not show a mirror reflection?

• Because it has a rough surface that diffuses light.

• Because it is not in direct sunlight.

• Because it is too far away.

• Because it is moving too fast.

What happens to light when it passes from air into water?

• It gets absorbed by the water.

• It reflects back into the air.

• It bends and travels downward.

• It scatters in all directions.

What is the term used to describe the bending of light as it passes from one medium to another?

• Absorption

• Refraction

• Diffusion

• Reflection

How does the absorption of light affect the colors we see?

• It makes all colors appear white.

• It allows us to see only the reflected colors.

• It makes all colors appear black.

• It allows us to see only the absorbed colors.

Which property of light is responsible for making objects appear bent in water?

• Absorption

• Diffusion

• Refraction

• Reflection

What is the relationship between the angle of incidence and the angle of reflection?

• They are always equal.

• They depend on the color of light.

• They are unrelated.

• They are always different.

Which of the following is NOT a property of light discussed in the video?

• Reflection

• Refraction

• Absorption

• Diffusion
