14 February 2016- Frequency | PWN Physics 365

On this day in physics: 14 February 1874 - The IOP, or Institute of Physics was founded. It's a 50,000 strong charity which furthers education and scientific research, as well as publishing many journals in the field of physics.

Word of the day- Frequency is the amount of repetitions something, most usually a wave, undergo in a certain period of time. Frequency is measured in Hertz, the unit of which is 1/s, or "stuff per time". In a wave, it is the amount of oscillations per unit of time. In waves, the frequency multiplied by the wavelength is equal to the velocity. This means the shorter the wave, the higher the frequency. The longer the wave, the lower the frequency. Radio waves are waves broadcast at very specific frequencies, and when you change your radio dial, you actually tune your radio to check for information at a different frequency of radio wave. F.M. stands for frequency modulation, meaning that in this type of radio wave, the frequency is tuned in order to change the stations.

Quote of the Day: "Physics isn't the most important thing. Love is." -Richard P. Feynman
