Answer #1

Problem - 6

Given is:-

Frequency of the sound is  f =500 Hz

The speed of the sound in air at room temperature and atmospheric pressure is c343m/s

Now,

the wavelength of a sound wave is given by

lambda = rac{c}{f}

by plugging all the values we get

343 500

λ 0.686771

    Two speaker emit the same pure tone at 170 Hz, but they are half a cycle out of phase with each other (so one produces a "trough" exactly when the other one produces a "crest"). The speakers are three meters apart. You are standing between the speakers, one meter from one (and therefore two meters from the other). What do you hear? The speed of sound in air is 340 m/s. O A 170 Hz tone, but very quietly, if...
