Understanding Light and Materials

What does the term "absorb" mean?

• To reflect light

• To soak up or take something in

• To allow light to pass through

• To bounce off a surface

What is "light energy"?

• Energy that allows us to see

• Energy that is absorbed by materials

• Energy that is reflected off surfaces

• Energy that is stored in batteries

The matter from which a thing is made

• reflect

• material

• object

• light

What is a "model"?

• A full-sized object

• A limited representation of something

• A type of material

• A type of energy

What is an "object"?

• Anything that is visible or able to be touched

• A type of energy

• A type of wave

What does "opaque" mean?

• A material that allows all light to pass through

• A material that does not allow any light to pass through

• A material that partially allows light to pass through

• A material that reflects light

The bouncing of energy waves off the surface of an object

• transparent

• Reflection

• refraction

What is "refraction"?

• The bouncing of energy waves

• The bending or redirection of energy waves as they pass from one substance to another

• The absorption of energy waves

• The reflection of energy waves
