Answer:
The correct answer is option A.
Explanation:
Wavelength is defined as distance between two successive crests of the wave.It is denoted by Greek letter [tex]\lambda [/tex] (lambda ).
It is calculated by dividend velocity of the waver from its frequency.
[tex]\lambda =\frac{Speed}{Frequency}[/tex]
In the given figure ;
The difference between two crest is = 2.5 cm - 2.5 cm = 10 cm.
The wavelength of the given wave is 1.0 cm.
