Light and Materials

What is a transparent material?

• A material that allows light to pass through without scattering

• A material that absorbs all light

• A material that changes color in different lighting

• A material that reflects all light

Give an example of a transparent material.

• Glass

• Brick

• Metal

• Wood

What is an opaque material?

• A material that does not allow light to pass through it.

• A material that is highly reflective of light

• A material that is transparent to sound

• A material that allows light to pass through it

Give an example of an opaque material.

• Wood

• Glass

• Plastic

• Air

What is a translucent material?

• Translucent material is a material that allows some light to pass through, but scatters the light in all directions.

• Translucent material is a material that absorbs all light and reflects none.

• Translucent material is a material that only allows light to pass through in one direction.

• Translucent material is a material that allows no light to pass through.

Give an example of a translucent material.

• Transparent water

• Clear plastic

• Opaque metal

• Frosted glass

How does light pass through a transparent material?

• The material reflects the light back towards the source

• The material absorbs the light and then releases it

• The material emits its own light to allow passage

• The atoms in the material are arranged in a way that allows light to travel through without being absorbed or scattered.

How does light pass through an opaque material?

• It does not pass through an opaque material.

• It creates a shadow when passing through

• It changes color when passing through

• It passes through easily

How does light pass through a translucent material?

• By changing color as it passes through

• By being reflected off the material's surface

• By being scattered and absorbed by the material's particles

• By passing through without any interaction

Explain the difference between transparent, opaque, and translucent materials.

• Translucent materials do not allow any light to pass through

• Transparent materials absorb light and do not allow it to pass through

• Opaque materials allow light to pass through with little scattering

• Transparent materials allow light to pass through with little or no scattering, opaque materials do not allow light to pass through, and translucent materials allow some light to pass through but also scatter the light.
