Essentially, you can make a wave (with the wave equation) for electric and magnetic fields in the same way that a wave moves on a string. The speed of this electromagnetic wave (in a vacuum) would ...

The equation can be written as follows: 1/v^2 * ∂^2y/∂t^2= ∂^2y/∂x^2. In this equation, v is the velocity of a wave, and the other parts describe the displacement of the wave in one direction.

Let's take a moment to see how this equation makes sense. ... Now using v = λf, we find a wave speed of 504.9 meters per second. What if I want to play a G note, or 391 Hz, ...

Seismic reflection method seeks to create an image of the Earths crust from recording of echoes stimulated for example by explosions. In contrast to medical sonography, seismic reflection method ...
