EM and Mechanical Waves

Front

What is the medium through which sound can travel?

Back

Sound can travel through solids, liquids, and gases.

Front

How are sound waves categorized?

Back

Sound waves are categorized as mechanical and longitudinal.

Front

What is the formula to calculate the wavelength of a wave?

Back

Wavelength (λ) = Speed (v) / Frequency (f)

Front

What is the wavelength of a sound wave with a frequency of 340 Hz traveling at 680 m/s?

Back

2.0 m

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

Can mechanical waves travel through a vacuum?

Back

No, mechanical waves cannot travel through a vacuum.

Front

What are the two main types of waves?

Back

Mechanical waves and electromagnetic waves.

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that can travel through a vacuum and does not require a medium.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation; in longitudinal waves, it is parallel.
