Light Behavior and Refraction Concepts

The video explores the dual nature of light, explaining how it behaves as both a wave and a particle. It delves into the wave behaviors of light, including reflection, refraction, and diffraction. Reflection is described as light bouncing off surfaces, while refraction involves light bending due to speed changes in different media. Diffraction is explained as the spreading of light when it passes through small openings. The video uses practical examples like mirrors, water, and prisms to illustrate these concepts, emphasizing the wave nature of light.

What is the dual nature of light as discussed in the video?

• Light is only a wave.

• Light is only a particle.

• Light behaves as both a wave and a particle.

• Light is neither a wave nor a particle.

How does light behave when it reflects off a surface?

• It changes color.

• It maintains the same angle and color.

• It disappears.

• It splits into different colors.

What causes light to bend during refraction?

• A change in temperature.

• A change in color.

• A change in medium.

• A change in direction.

Why does a pencil appear bent when placed in a glass of water?

• Because of refraction.

• Because of absorption.

• Because of diffraction.

• Because of reflection.

In bow fishing, why do you need to aim lower than the apparent position of the fish?

• Because fish move quickly.

• Because water distorts the size of the fish.

• Because light refracts and bends in water.

• Because light reflects off the water surface.

What phenomenon causes the formation of rainbows?

• Diffraction of light.

• Reflection of light.

• Absorption of light.

• Refraction and dispersion of light.

How does light behave when it passes through a diffraction grating?

• It changes speed.

• It splits into its component colors.

• It reflects back.

• It disappears.

What is the key difference between refraction and diffraction?

• Refraction involves a change in medium, diffraction does not.

• Diffraction involves a change in medium, refraction does not.

• Neither involves a change in medium.

• Both involve a change in medium.

Which of the following is NOT a wave behavior of light?

• Refraction

• Reflection

• Absorption

• Diffraction

What happens to light when it passes through a small opening in a diffraction grating?

• It gets absorbed.

• It slows down.

• It speeds up.

• It spreads out and splits into colors.
