Electromagnetic radiation

can be described as periodically changing transportation of

energy

through

space

. The length of one

period

is known under the term

wavelength

. The time of the oscillation necessary for completion of one period-length is defined by the term

frequency

; it has the unit of 1/seconds. Since the time of an object traveling a certain amount of length through space, is determined by its

speed

, the conversion of wavelength to frequency is likewise dependent on the speed. This leads to the

inverse

dependence of

wavelength

and

frequency

.
The interactive Graph on this page allows for

conversion

of wavelength to frequency (top) and the visualization of the

electromagnetic wave

in space and time.
Because of the

particle nature

, electromagnetic radiation can also be expressed in terms of

energy (eV)

, as multiple of the

Planck`s constant h

.

Another representation of frequency and wavelength is to be found in the expression

Bandwidth

. An

electromagnetic signal

often consists of a bundle of different

frequencies components

. The information of the spectral representation is given by the difference between highest and lowest frequency (or wavelength). Owing to the

inverse relationship

of these magnitudes, the magnitude of

bandwidth

shows similarly no linear proportionality between

bandwidth

in

wavelength

and

frequency

.
The interactive Graph on this page (bottom) allows for conversion of bandwidth from wavelength to frequency and the visualization of the

distribution

function.
