Unit 3: WAVES

Front

What determines the loudness of sound?

Back

Amplitude determines the loudness of sound.

Front

What determines the pitch of sound?

Back

Frequency determines the pitch of sound.

Front

Which wave has the greatest amplitude?

Back

Wave E has the greatest amplitude.

Front

What is reflection in the context of waves?

Back

Reflection occurs when a wave bounces back after hitting a barrier.

Front

Through which medium does sound travel fastest?

Back

Sound travels fastest through solids, such as metal.

Front

What happens to the sound wave if the amplitude decreases?

Back

The sound wave becomes softer.

Front

What is the relationship between frequency and wavelength?

Back

Higher frequency means shorter wavelength.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves move perpendicular to the direction of energy transfer, while longitudinal waves move parallel.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.
