Question

What is the wave length?

Answer 1

Distance between Wave Peaks..[high points] is called wave length

Answer 2

Wavelength :-

                     ⇒The distance between any two compression or rarefaction is known as waavelength.
               
                       ⇒The higher the frequency the shorter the the wavelength and higher the wavelength shorter the frequency
                 
                         ⇒The S. I unit of wavelength is metre.
