Wave

• A material that allows light to pass through completely

• The bending of light when it passes from one material to another.

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

• A disturbance that transfers energy from one place to another.

Refraction

• A material that allows light to pass through completely.

• The speed at which a wave travels through a medium

• The bending of light when it passes from one material to another

• The spreading out of waves as they move around a barrier or through an opening

Opaque

• A material in which light does not pass through

• A material that allows some light to pass through but not completely

• A material that allows light to pass through completely

• The spreading out of waves once they hit a barrier or an opening

Transparent + (choose an example)

• A material that does allow light to pass through but not completely

• PNG. It is called png because when inputting inside a program (e.g. CapCut or Ibispaintx) the background is invisible only the object itself.

• Air, Air contains mass and particles which the sunlight is partially blocked from reaching the ground

• A material that does allow light to pass through completely

Reflection

• A material that does not allow light to pass through

• The bouncing back of a wave when it hits a surface it cannot pass through

• The material at which through a wave travels

• A disturbance that transfers energy from one place to another

Wave speed

• The number of waves that passes through in a given time

• The speed at which a wave travels through a medium

• The distance between two corresponding points on a wave, such as crest to crest.

• The spreading out of waves as they move around a barrier or through an opening.

What is Diffraction?

• The bending of light when it passes from one material to another.

• The distance between two corresponding points on a wave, such as crest to crest.

• The spreading out of waves as they move around a barrier or through an opening.

• The bouncing back of a wave when it hits a surface it cannot pass through.

The distance between one crest and the next crest of a wave is called the

Light as it passes through water is an example of

The height of a wave is its _, which is related to the wave's energy.
