Two loudspeakers, a and b, are driven by the same amplifier and emit sinusoidal waves in phase. speaker b is 2.00 m to the right of speaker a. consider point q along the extension of the line connecting the speakers, 1.00 m to the right of speaker b. both speakers emit sound waves that travel directly from the speaker to point q. a) what is the lowest frequency for which constructive interference occurs at point q? b) what is the lowest frequency for which destructive interference occurs at point q?

Answer

a) For constructive interference, the path difference must be equal to an integer multiple of the wavelength, so

frequency

the lowest frequency is 172 Hz. for ( n = 1)

b) Repeating the above with the path difference an odd multiple of half a wavelength,

the lowest frequency is 86 Hz ( n = 0)

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

explanation:

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
