Frequency and Wavelength Calculator

Frequency is a measure of the number of times a recurring event occurs per unit of time.

The unit of frequency is hertz (Hz), named after the German physicist Heinrich Hertz. Hertz is one cycle per second, 100 hertz, one hundred hertz, etc.

Wavelength is the distance between repeating units of a wave of a given frequency. The symbol λ can be used as the wavelength. Examples of ripple phenomena are light, water waves and sound waves

Wavelength can be expressed in any unit of length such as meters, feet, centimeters, etc.

The speed of light in vacuum is an important physical constant, designated by the letter C.

In metric units, the speed of light in a vacuum is 299792458 meters per second (1079252848.8 km/h). In imperial units, the approximate value is 3×10<sup>8</sup> m/s. The speed of light is 983571056 feet per second per hour. About 670616629.2 miles, which is about 186282.397 miles per second, which is about one foot per nanosecond.
