Wave Speed in Different Mediums

Front

What is the primary difference between mechanical waves and electromagnetic waves?

Back

Mechanical waves require a medium (solid, liquid, or gas) to travel, while electromagnetic waves can travel through a vacuum.

Front

In which medium do electromagnetic waves, like X-ray light, travel the fastest?

Back

Electromagnetic waves travel fastest in air.

Front

Which medium allows electromagnetic waves to travel at the lowest speed?

Back

Electromagnetic waves travel at the lowest speed in diamond.

Front

Through which material does sound travel the fastest?

Back

Sound travels fastest through metal.

Front

Why is sound unable to travel in space?

Back

Sound cannot travel in space because it is a mechanical wave and requires a medium to propagate.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

How does temperature affect the speed of sound in a medium?

Back

The speed of sound increases with an increase in temperature in a given medium.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed is equal to the product of frequency and wavelength (v = f × λ).

Front

What type of wave is sound classified as?

Back

Sound is classified as a mechanical wave.

Front

Can electromagnetic waves travel through a vacuum?

Back

Yes, electromagnetic waves can travel through a vacuum.
