Sound waves /amplitude flashcard

Front

What is the highest point on a wave called?

Back

Crest

Front

What happens to sound when the amplitude of a wave increases?

Back

The sound gets louder.

Front

Which color of light has the lowest wavelength?

Back

Violet

Front

What is the lowest point on a wave called?

Back

Trough

Front

What is the horizontal distance between crests of a wave?

Back

Wavelength

Front

What is amplitude in the context of sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound.

Front

What is frequency in relation to sound waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

How does wavelength relate to the pitch of a sound?

Back

Shorter wavelengths correspond to higher pitches, while longer wavelengths correspond to lower pitches.

Front

What is the relationship between amplitude and energy in a wave?

Back

Higher amplitude means more energy is carried by the wave.

Front

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

Back

Speed = Wavelength x Frequency.
