Diffraction angle of sound after it passes during doorway

Reference no: EM13679762

The entrance to a large lecture room consists of two side-by-side doors, one hinged on the left and the other hinged on the right. Each door is 0.680 m wide. Sound of frequency 646 Hz is coming through the entrance from within the room. Take the speed of sound to be 345 m/s. What is the diffraction angle of the sound after it passes during the doorway when (a) one door is open and (b) both doors are open?

What is the new fundamental frequency of the tube : A tube with a cap on one end, but open at the other end, has a fundamental frequency of 130.7 Hz. The speed of sound is 343 m/s. a) If the cap is removed, what is the new fundamental frequency of the tube? (b) How long is the tube?

What is the fundamental frequency of this wire : A 50-cm length of wire has a mass of 8.6 g. It is stretched among two fixed supports and is under a tension of 200 N. What is the fundamental frequency of this wire?

Low-frequency moaning sound is produced : Sometimes, when the wind blows across a long wire, a low-frequency "moaning" sound is produced. This sound arises because a standing wave is set up on the wire, like a standing wave on a guitar string. Suppose that a wire (linear density = 0.0140 kg/..

What is wavelength of the waves that travel on the string : A string that is fixed at both ends has a length of 2.28 m. When the string vibrates at a frequency of 85.7 Hz, a standing wave with five loops is formed. (a) What is the wavelength of the waves that travel on the string? (b) What is the fundamental ..

Diffraction angle of sound after it passes during doorway : The entrance to a large lecture room consists of two side-by-side doors, one hinged on the left and the other hinged on the right. Each door is 0.680 m wide.

Decide the frequency of the sound coming from the speakers : A listener is standing in front of two speakers that are producing sound of the same frequency and amplitude, except that they are vibrating out of phase. Initially, the distance among the listener and each speaker is the same (see the drawing).

Speed-stationary source of sound and hear a frequency : You are riding your bicycle directly away from a stationary source of sound and hear a frequency that is 2.6% lower than the emitted frequency. If the speed of sound is 342 m/s, what is your speed?

Discover the maximum stretch of the spring xmax : A simple harmonic oscillator consists of a 0.10 kg mass attached to a spring whose force constant is 0.30 N/m. The mass is displaced 0.50 meters from equilibrium in the positive x-direction (stretching the spring) and is given a positive initial velo..

What angle relative to the north-south direction : Canadian geese migrate essentially along a north-south direction for well over a thousand kilometres in some cases, traveling at speeds up to about 100 km/h. If one such bird is flying at 100 km/h relative to the air, but there is a 30.0km/h wind blo..
