Unit 6:1 Lesson 3 Light Investigation

What is reflection of light?

• Reflection of light is the process by which light bounces off a surface and changes direction.

• Reflection of light is the process by which light passes through a surface and continues in the same direction.

• Reflection of light is the process by which light is absorbed by a surface and disappears.

• Reflection of light is the process by which light is emitted from a surface and spreads out in all directions.

Explain the law of reflection.

• The law of reflection states that the angle of incidence is less than the angle of reflection

• The law of reflection states that the angle of incidence is greater than the angle of reflection

• The law of reflection states that the angle of incidence is unrelated to the angle of reflection

• The law of reflection states that the angle of incidence is equal to the angle of reflection when light or any other wave reflects off a surface.

Give an example of reflection of light in everyday life.

• Looking at yourself in the mirror

• Light bouncing off a window

• Reflection of light in a vacuum

• Seeing your reflection in a puddle

What is refraction of light?

• Refraction of light is the absorption of light by a medium.

• Refraction of light is the bending of light as it passes from one medium to another.

• Refraction of light is the reflection of light off a surface.

• Refraction of light is the scattering of light as it passes through a medium.

How does the speed of light change when it enters a different medium?

• The speed of light remains constant when it enters a different medium

• The speed of light decreases when it enters a different medium

• The speed of light increases when it enters a different medium

• The speed of light changes when it enters a different medium due to the change in the medium's refractive index.

Provide an example of refraction of light in nature.

• Light passing through water

• Light passing through a vacuum

• Light passing through a solid object

• Light passing through a mirror

What is absorption of light?

• Absorption of light is the process of light turning into sound

• Absorption of light is the process of light creating more light

• Absorption of light is the process in which a material takes in light energy and transforms it into other forms of energy, such as heat.

• Absorption of light is the process of light escaping from a material

How does the color of an object relate to its absorption of light?

• The color of an object is related to the speed of light it absorbs

• The color of an object is related to the sound waves it absorbs

• The color of an object is related to the specific wavelengths of light that it absorbs and reflects.

• The color of an object is related to the temperature of the light it absorbs

Give an example of a material that absorbs light well.

• Aluminum foil

• Carbon black

• White paper

• Clear glass

Explain how the three processes of reflection, refraction, and absorption are important in our daily lives.

• These processes are important in our daily lives as they are involved in music production, energy generation, and waste management.

• These processes are important in our daily lives as they are involved in phenomena such as vision, cooking, and communication.

• These processes are important in our daily lives as they are involved in earthquake formation, space exploration, and animal behavior.

• These processes are important in our daily lives as they are involved in weather patterns, plant growth, and transportation.
