What is a Jewish baby naming ceremony? This is a brief ceremony during which the baby is given his or her Hebrew name. The chosen Hebrew name could be a name that sounds like the baby's secular/English name, or one that begins with the same sound as the baby's secular/English name.
For  radio waves and light waves  â scroll down â. Conversion: frequency f to wavelength Î» and wavelength to frequency. The speed of propagation c can be the speed of sound *or* the speed of light and radio waves. Sound waves are waves which propagate vibrations of air molecules.
The following equations hold true between frequency, wavelength and sound velocity : If the frequency of a sound is 440 Hz (the tone A1) and the velocity of the sound is approximately 330 m/s, its wavelength is 0.75 metres (or 75 centimetres). The successive compressions of the sound wave are 75 centimetres apart. Sound velocity depends on medium (such as metal, water or air) and temperature.
