Electromagnetism - Problems – The Physics Hypertextbook
The source of all magnetism is moving charge. Currents deep in the earth gives it a magnetic field. Spinning electrons are why iron bars are magnets.
Problem Set - Physics
Problem 20: In the Standing Wave Lab, lab partners Chloe and Paige adjust the frequency of a mechanical oscillator in order to vibrate a 1 m length of elastic cord at one of its harmonic frequencies. The cord vibrates with the pattern shown below when the frequency is set to 79.4 Hz. Determine the speed of the waves in the elastic cord.
Module 3 - The Electromagnetic Radiation - Problems
Electromagnetic Wave Problems (4) Solution in detail below: First we need to consider what would be the best equation to use. Obviously, the equation involving energy change, Plank's constant, and frequency is the best way to go. Next, we need to figure out what we are solving for.
