WebWe assume you are converting between speed of light [air] and centimetre/second. You can view more details on each measurement unit: speed of light or cm/s The SI derived unit for speed is the meter/second. 1 meter/second is equal to … WebAs it is a type of light it moves at the speed of light. Speed, wavelength and frequency are closely related, as described in diagram 2: So this means that if the wave has a frequency of 100 Hz it will travel its wavelength 100 times in a second. So the speed of a wave is its frequency multiplied by its wavelength.

According to the special theory of relativity, c is the upper limit for … See more The speed of light in vacuum is usually denoted by a lowercase c, for "constant" or the Latin celeritas (meaning 'swiftness, celerity'). In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different constant … See more In classical physics, light is described as a type of electromagnetic wave. The classical behaviour of the electromagnetic field is described by Maxwell's equations, which predict that … See more There are different ways to determine the value of c. One way is to measure the actual speed at which light waves propagate, which can be done in various astronomical and … See more The speed at which light waves propagate in vacuum is independent both of the motion of the wave source and of the inertial frame of reference of the observer. This invariance of … See more There are situations in which it may seem that matter, energy, or information-carrying signal travels at speeds greater than c, but they do not.
