frequency cm 1 to s 1
What is the frequency of 1cm wavelength?
For example, a wavenumber in inverse centimeters can be converted to a frequency in gigahertz by multiplying by 29.9792458 cm/ns (the speed of light, in centimeters per nanosecond); conversely, an electromagnetic wave at 29.9792458 GHz has a wavelength of 1 cm in free space.
To calculate the wavenumber, divide the frequency by the speed of light.
The result is the wavenumber in inverse centimeters (cm-1).16 oct. 2023
What is 1 s in frequency?
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second.
The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second.
