Answer:
The correct answer is option A.
Step-by-step explanation:
Wavelength is defined as distance between two successive crests of the wave.It is denoted by Greek letter
(lambda ).
It is calculated by dividend velocity of the waver from its frequency.
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.
