Hey i need help with my physics homework please cause I've been struggling with these questions.
A student sets up the apparatus as shown here, to investigate the properties of sound waves. A burning candle is placed next to a bell glass with an opening that is connected to a vacuum pump. A loudspeaker is placed inside the bell glass and connected to an electric current that causes the cone or surface of the loudspeaker to vibrate and propagates a sound wave of maximum volume. The vacuum pump is off.
1.1 explain how the loudspeaker can propagate a sound wave.
1.2 what happens to the candle flame?
1.3 how does the air particles move around the candle flame as a result of the sound waves that are propagated by the loud speaker?
1.4 are sound waves transverse or longitudinal waves? Explain.
1.5 after the acuum pump is switched on waht happens to the candle flame? Explain shotly.
1.6 what can be derived from the propagation of sound waves from your answer in question 1.4?
1.1 The loudspeaker propagates a sound wave by vibrating back and forth, which causes the air particles around it to also vibrate. This creates a pressure wave that travels through the air as sound.
1.2 The candle flame will flicker and dance as a result of the vibrations caused by the sound waves.
1.3 The air particles around the candle flame will move back and forth in the same direction as the sound wave, causing the flame to move in response to the pressure changes in the air.
1.4 Sound waves are longitudinal waves, as the vibrations of the medium (in this case, air) are parallel to the direction of the wave's propagation. This means that the air particles move in the same direction as the wave, causing compressions and rarefactions.
1.5 When the vacuum pump is switched on, the air inside the bell glass is removed, creating a partial vacuum. This reduces the medium through which the sound waves can travel, dampening the vibrations and reducing the pressure changes in the air. As a result, the candle flame will likely stabilize and appear less affected by the sound waves.
1.6 From the propagation of sound waves and the behavior of the candle flame, we can derive that sound waves require a medium to travel through, and that changes in pressure and vibrations in the medium can affect objects within that medium.
