Light Behavior: Reflection and Refraction

The video tutorial explores the behavior of light, focusing on reflection and refraction. It begins with an optical illusion involving paintbrushes in water, leading to a discussion on how light interacts with different surfaces and mediums. The lesson covers reflection, including specular and diffuse reflection, and refraction, explaining how light bends when entering different mediums. The tutorial concludes with a summary of these concepts and a brief introduction to diffraction.

What phenomenon causes the paintbrushes to appear bent when placed in water?

• Absorption

• Refraction

• Diffraction

• Reflection

What is the primary cause of reflection?

• Light waves spreading out

• Light waves bending

• Light waves bouncing off surfaces

• Light waves being absorbed

Which type of reflection occurs on a smooth, shiny surface?

• Diffuse reflection

• Specular reflection

• Scattered reflection

• Refracted reflection

Why can't you see your reflection on a concrete wall?

• Specular reflection occurs

• Diffuse reflection occurs

• The wall is too smooth

• The wall absorbs all light

What happens to light when it enters a different medium?

• It speeds up

• It bends

• It gets absorbed

• It remains unchanged

How does a prism separate white light into different colors?

• By bending the light at different angles

• By reflecting the light

• By absorbing certain colors

• By speeding up the light

Why do objects underwater appear at a different location than they actually are?

• Because of refraction

• Because of absorption

• Because of diffraction

• Because of reflection

What is the effect of light bending when it enters water?

• Objects appear unchanged

• Objects appear bent

• Objects appear smaller

• Objects appear larger

What is diffraction?

• Light waves spreading out after passing through a narrow space

• Light waves being absorbed by a medium

• Light waves bouncing off a surface

• Light waves bending when entering a new medium

What will the next lesson focus on?

• A hands-on lab

• A theoretical discussion

• A video demonstration

• A written test
