Wave Behaviors

Why do we see colors?

• We see colors because different wavelengths of light are absorbed or reflected by objects, determining their color appearance.

• We see colors because our eyes produce pigments that create color perception.

• We see colors due to the temperature of the objects we observe.

• We see colors because of the emotional responses they evoke in us.

What is diffraction?

• The reflection of light waves off surfaces.

• The bending of light waves around obstacles or through openings.

• The absorption of light waves by materials.

• The scattering of light waves in different directions.

What happens to light waves when they strike dark material?

• Light waves are reflected, bouncing off the surface.

• Light waves are transmitted, passing through the material.

• Light waves are absorbed by the dark material, converting their energy into thermal energy.

• Light waves are scattered in multiple directions.

In which medium does light travel fastest?

• In solid

• In liquid

• In gas

• In vacuum

What is transmission in terms of light?

• Transmission is the process by which light waves pass through a material without being absorbed.

• Transmission refers to the reflection of light off a surface.

• Transmission is the absorption of light by a material.

• Transmission is the scattering of light in different directions.

What is the purpose of darker sunglasses lenses?

• To completely block out all light for better visibility

• To absorb light to reduce glare while still allowing some light to transmit

• To enhance color perception in bright environments

• To provide a fashion statement without any functional benefit

What is the difference between reflection and refraction?

• Reflection is when light bounces off a surface, while refraction is when light bends as it passes through a medium.

• Reflection occurs when light passes through a medium, while refraction is when light bounces off a surface.

• Reflection and refraction are the same phenomena occurring at different angles.

• Reflection is the bending of light, while refraction is the bouncing of light off surfaces.

What is refraction?

• The reflection of light waves off a surface.

• The bending of light waves as they pass from one medium to another.

• The scattering of light waves in different directions.

• The absorption of light waves by a medium.

Why does a polar bear's head appear separate from its body in water?

• Light waves bend as they pass from air to water, causing the visual distortion.

• The polar bear's body is submerged, making its head look detached.

• The polar bear's fur creates an optical illusion in water.

• The water's surface reflects light differently than air does.

How does temperature affect the speed of sound compared to light?

• Sound travels faster than light and is unaffected by temperature.

• Sound travels slower than light, and its speed can be affected by temperature, while light's speed remains constant in a vacuum.

• Temperature has no effect on the speed of sound or light.

• Light travels slower than sound, and its speed can be affected by temperature.
