SSC MTS EXAM

Detailed explanation-1: -Wavelength is usually denoted by the Greek letter lambda (); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): = v/f.

Detailed explanation-2: -Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda , so = v/f. So the SI unit of wavelength is Meter(m). Was this answer helpful?

Detailed explanation-3: -When wavelength is measured in metres, 1/ represents the number of waves of the wave train to be found in a length of one metre or, if measured in centimetres, the number in one centimetre. This number is called the wavenumber of the spectrum line.

Detailed explanation-4: -It’s the Greek equivalent of L, so it was chosen to denote the length of a wave.
