Maxwells Fields

Example 1: Wave Properties in Everyday Life

The Question:

What are the wavelengths of:

  1. the lowest C on a piano (32.7 Hz);
  2. WKAR AM radio radiation (871 kHz on your radio dial)?

Assume that the speed of sound in air is 341 m/s and that the speed of light in a vacuum is m/s.

The Answer:

We can easily use the relation for wavelength, frequence, and wave speed twice to find these.
