When one mirror of a Michelson interferometer is moved a distance of 0.5 mm, 2000 fringes are observed, Find the wavelength of the light used. Please explain step by step.
A photon of energy E collides with an electron at rest. Calculate the maximum amount of energy Ek that may be transfered to the electron. Make a graph of Ek versus E, labeling the scale in electron volts.
An outside loudspeaker (considered a small source) emits sound waves with a power output of 100 W. (a) Find the intensity 10.5 m from the source. W/m2 (b) Find the intensity level in decibels at that distance. dB (c) At what distance would you experi..
