Many different things can move like waves like strings water the air sound waves the ground earthquakes and light can be treated as a wave. The Frequency is expressed in Hertz Hz. A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillationA sine wave is a continuous waveIt is named after the function sine of which it is the graphIt occurs often in both pure and applied mathematics as well as physics engineering signal processing and many other fields.
V f l where v speed of f frequency l wavelength.
Formula to calculate wave period from wave length l and speed. L vf where. The formula for angular frequency is the oscillation frequency f measured in oscillations per second multiplied by the angle through which the body moves. Frequency Formula Frequency is the number of cycles in a unit of time.
