Does the velocity of sound in air depend on the frequency of the sound? Explain. Consider what you would hear if the high and low pitched notes made by musicians took different times to reach your ear?

No. The frequency is decided by the oscillating body producing the sound waves. The speed of a wave(including sound) is decided by the elastic/inertial properties of medium. While as speed of sound is different in different media, the frequency of a particular sound wave remains same in all media.

Pitch of a sound note is characterised by the frequency of the sound wave. Both high pitch and low pitch notes will reach our ear simultaneously. If this were not so, it will create mess and the result will not be musical anymore but irritating mess for the ears.
Speed of a wave may depend upon the frequency of the wave in a medium known as dispersive medium. But, air is not a dispersive medium for sound waves.

Two speakers that are 15m apart produce in phase sound waves of frequency 250Hz in a room where the speed of sound is 340m/s. A woman starts out at the midpoint between the two speakers . The room's walls and ceiling are covered with absorbers to eliminate reflections, and she listens with only one ear for best precision. (a) What does she hear: constructive or destructive interference? (b) she now walks slowly toward one of the speakers. How far from...

1. Consider a speaker at some fixed position, emitting sound uniformly in all directions. You are standing at some distance d from this speaker, holding a sound-intensity measuring device. You then walk 25.0 m in a straight line towards the speaker. At this point you observe that the intensity of the sound has doubled (from the previous location). Determine the distance d. There are no echoes or reflections or interference. 2. You are standing equidistant from four identical jet engines...

Suppose you are listening to a sound with frequency of 200 Hz and amplitude of 20 μPa. What is the SPL of that sound (please express your result in dB) [Hint: use the formula SPL=20log10(A/Ao) where Ao=20micro pascals Do you think you would be able to perceive this sound? Explain your answer. [Hint: you will need to look at the Fletcher-Munson diagram]

Someone on the deck of a pool is playing a guitar while you are underwater. How does the sound wave differ after it enters the water when you hear it as compared to the sound wave before entering the water? Include as many variables as possible in your explanation (velocity, frequency, wavelength, amplitude, energy, direction, period). Please explain fully. I am confused since I know waves move faster in a less dense medium. However, water is denser than air, but...

2 Amplitude Modulation When two musical notes are nearly the same pitch, one can hear “beats” — a periodic rise and fall in the volume of a single pitch. (a) Generate a plot of this phenomenon. Create — and upload — a graph of the waveform f(t) that results from superposition of two waves with similar frequencies: f1(t) =cos21t, f2(t) =cos19t, f(t) = f1(t)+f2(t) (b) Describe the significant features of your plot. What pitch would you hear? At what frequency...

You can sometimes hear a low-frequency “moaning” noise when strong winds blow through power lines strung between two poles. The wind is exciting a particular standing wave mode on the wire between its fixed ends at the poles; in this example, the wire is observed to have the shape shown in the diagram below at a particular instant in time. (a) If, for this mode (or harmonic), the frequency you hear is 20 Hz (near the lower threshold of human...

Most sound sources are considered point sources, and sound will spread spherically away from the source in the air. Consider the surface area of a sphere. What is the formula for the surface area of a sphere? If you don’t remember this, please look this up on the internet or in the reference section of your textbook. How does this explain the intensity of sound as you move away from a point source?

Please show all your work. A source of sound is located in a room a distance “L” from a wall. The room temperature is 72°F. AN observer is located between the source and the wall at 103 cm from the wall. The observer can hear a loud sound at the 3rd harmonic and the sound fades at the 4th harmonic. What is the velocity of sound in the room? What is the frequency at which the observer can hear the...
