Modeling Waves through Mediums

Front

What is an echo?

Back

An echo is a reflected sound wave that is heard after the original sound has been produced.

Front

What happens to light when it is reflected?

Back

When light is reflected, it bounces off a surface instead of being absorbed.

Front

What happens to light when it is absorbed?

Back

When light is absorbed, it is taken in by a material and converted into other forms of energy, such as heat.

Front

Why does sound travel faster through solids than through gases?

Back

Sound travels faster through solids because solid molecules are packed tightly together, allowing sound waves to transfer more quickly.

Front

Which statement about sound waves is true?

Back

Sound waves can be reflected.

Front

What is a medium in the context of waves?

Back

A medium is a substance through which a wave travels, such as air, water, or solid materials.

Front

What is the difference between frequency and pitch?

Back

Frequency is the number of waves that pass a point in a given time, while pitch is how high or low a sound is perceived.

Front

What is rarefaction in a sound wave?

Back

Rarefaction is the part of a sound wave where the particles are spread apart, resulting in lower pressure.

Front

What is the speed of sound in air compared to water?

Back

The speed of sound is slower in air than in water because water is denser than air.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.
