Question
Please include an equation and an explanation or reasoning that supports the given conditions.
A guiter string is the note B (frequency = 218 Hz) in our physics classroom where the temperature is 20 degree C. Describe qualitatively what will happen to the note a listener will hear under each of the following conditions. Support your answer with an equation or reasoning. The tension in the string is increased. The tension in the string is increased. The temperature in the room is increased The note is played as the guitar is placed into a car speeding at 40 m/s away from the school The air in the room is humidified The string is "fretted" at its half-way point (i.e., the effective length is halved) The guitar is somehow played after it is placed into a large vacuum jar and the air is evacuated The guitar is played again in the vacuum jar, but this time we fill the jar with helium The guitar string is replaced with a thicker string that is the same length and at the same tensionExplanation / Answer
a) If the tension is increased than the frequency of the sound produced will increase.
b) If the temperature of the room is increased than the frequency of the sound will decrease.
c) The frequency recieved by the listener will reduce because of the dopplers effect.
d) If the air is humified then the frequency of the sound produced will increase.
e) If the length is halved than the frequency of the sound produced will decrease by sqrt(2).
f).No sound will be produced, due to lack of medium.
g) The frequency of produced soumd will be tripled.
h) The frequency is inversely proportional to mass density and thus it will get reduced.
