1. Homework Statement The figure shows 1.0*10^-6 m diameter dust particles in a vacuum chamber. The dust particles are released from rest above a 1.0*10^-6 m diameter hole, fall through the hole (there's just barely room for the particles to go through), and land on a detector at distance d...

Thanks for the response. I see what you say but I can't find any way to find the second equation in order to find n . The way I was seeing it is that the crest of the wave that hits the points does not belong to the same wave but to consecutive waves in the same train wave. Otherwise, the speed...

Homework Statement A loudspeaker at the origin emits sound waves on a day when the speed of sound is 340 m/s. A crest of the wave simultaneously passes listeners at the{xy} coordinates (43 ,0) and (0,33).What are the lowest two possible frequencies of the sound? Homework Equations v(sound)=...
