Lexy says that the diffraction angle is the one labeled R, and Jin says that the diffraction angle is the one labeled S. Which best explains who is correct? Lexy is correct because angle R is between the incident wave, n = 0, and a diffracted wave. Lexy is correct because angle R includes the diffracted wave at n = 1. Jin is correct because angle S is measured from the barrier and includes n = 2, the wave that has the most diffraction. Jin is correct because angle S is between the dimmest order bands, n = 1 and n = 2.

Aheavy piece of hanging sculpture is suspended by a90-cm-long, 5.0 g steel wire. when the wind blows hard, the wire hums at its fundamental frequency of 80hz. what is the mass of the sculpture?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
