How is pitch related to frequency?

• Pitch is only related to amplitude, not frequency.

• Pitch has no relation to frequency.

• Pitch is directly related to frequency.

• Pitch is inversely related to frequency.

What is the difference between amplitude and volume?

• Amplitude refers to the frequency of a wave, while volume refers to the pitch of a sound.

• Amplitude refers to the brightness of a light wave, while volume refers to the intensity of a sound.

• Amplitude refers to the length of a wave, while volume refers to the duration of a sound.

• Amplitude refers to the maximum displacement of a wave from its equilibrium position, while volume refers to the perceived loudness of a sound.

What is resonance and how does it relate to vibration?

• Resonance is the phenomenon that occurs when an object or system is subjected to an external force that does not match its natural frequency, causing it to vibrate with increased amplitude.

• Resonance is the phenomenon that occurs when an object or system is subjected to an external force that matches its natural frequency, causing it to vibrate with increased amplitude.

• Resonance is the phenomenon that occurs when an object or system is subjected to an external force that matches its natural frequency, causing it to vibrate with decreased amplitude.

• Resonance is the phenomenon that occurs when an object or system is not subjected to any external force, causing it to vibrate with increased amplitude.

How does sound transmit through different mediums?

• Sound transmits through different mediums by emitting light waves.

• Sound transmits through different mediums by traveling through the air.

• Sound transmits through different mediums by creating vibrations or waves that travel through the molecules of the medium.

• Sound transmits through different mediums by changing its frequency.

What is the wavelength of a sound wave?

• The height of the wave

• The speed of the wave

• Distance between two consecutive points in the wave

• Distance between two random points in the wave

How does the frequency of a sound wave affect its pitch?

• The frequency of a sound wave has no effect on its pitch.

• The frequency of a sound wave directly affects its pitch.

• The higher the frequency of a sound wave, the lower its pitch.

• The frequency of a sound wave affects its volume, not its pitch.

What is the difference between mechanical and electromagnetic waves?

• Mechanical waves are used for communication, while electromagnetic waves are used for energy transmission.

• Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

• Electromagnetic waves require a medium to travel through, while mechanical waves can travel through a vacuum.

• Mechanical waves can travel faster than electromagnetic waves.

How does the speed of sound change in different mediums?

• The speed of sound changes in different mediums due to the difference in their color.

• The speed of sound changes in different mediums due to the difference in their temperature.

• The speed of sound changes in different mediums due to the difference in their weight.

• The speed of sound changes in different mediums due to the difference in their density and elasticity.
