PS4.2 Wave Behaviors Review for TEST

Front

What type of waves are sound waves and ocean waves?

Back

Mechanical waves; they need a medium to travel.

Front

Do all types of waves travel at the same speed?

Back

Yes, they all travel at the same speed.

Front

What are the three wave behaviors represented in the following order: 1, 2, 3?

Back

1: Transmission, 2: Absorption, 3: Reflection.

Front

What does the Tyndall Effect explain about light in liquids?

Back

Light may not be visible in water because the particles are too small for reflection.

Front

What happens to a wave when it is refracted?

Back

It can speed up, slow down, and/or change direction due to changes in the density of the medium.

Front

What is a mechanical wave?

Back

A wave that requires a medium (solid, liquid, or gas) to travel.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of waves, while refraction is the bending of waves as they pass from one medium to another.

Front

What is diffraction?

Back

The bending of waves around obstacles or through openings.

Front

What is the definition of absorption in wave behavior?

Back

Absorption is when a wave's energy is taken in by the medium, reducing its intensity.

Front

What is the role of density in wave behavior?

Back

Density affects how fast a wave travels through a medium; changes in density can cause refraction.
