Problem: Multiple-Concept Example 9 reviews the concepts that are important in this problem. An electron, traveling at a speed of 5.39 x 107 m/s, strikes the target of an X-ray tube. Upon impact, the electron decelerates to one-quarter of its original speed, emitting an X-ray in the process. What is the wavelength of the X-ray photon?
I want you to explain the physics in this problem.
A resonant circuit in a radio receiver is tuned to a certain station when the inductor has a value of 0.108 mH and the capacitor has a value of 33.6 pF. Calculate the frequency of the radio station
