DOL 3; Sound Waves

Front

What happens when waves hit a solid boundary that is free to move?

Back

The waves are reflected, bouncing back in the opposite direction while maintaining the same amplitude.

Front

What is the phenomenon called when waves bend around the edges of a small gap?

Back

Diffraction.

Front

Why can't you hear sounds in outer space?

Back

Because there is no medium for the sound waves to travel through.

Front

What do all waves carry as they travel from one place to another?

Back

Energy.

Front

What is any material that a wave travels through called?

Back

Medium.

Front

What is reflection in the context of sound waves?

Back

It is the bouncing back of sound waves when they hit a solid boundary.

Front

What is diffraction in wave behavior?

Back

It is the bending of waves around obstacles or openings.

Front

What is the role of a medium in sound wave propagation?

Back

A medium is necessary for sound waves to travel; without it, sound cannot be heard.

Front

Can sound waves travel through a vacuum? Why or why not?

Back

No, sound waves cannot travel through a vacuum because there is no medium.

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.
