The wavelength of the wave is 2.57 meters.
Explanation :
wavelength of a wave is defined as the distance between two successive crest.
Hence From third crest to tenth crest, distance = (10-3)λ = 7λ
given that the distance between third crest and tenth crest is approximately 18m
=> 7λ = 18
=> λ = 18/7 = 2.57 m
Hence the wavelength of the wave is 2.57 meters.
