Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.70 meter from the grating.
In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 3.10 millimeter. Compute the difference between these wavelengths?
A pair of speakers separated by 0.820 m are driven by the same oscillator at a frequency of 652 Hz. An observer originally positioned at one of the speakers begins to walk along a line vertical to the line joining the speakers.
