Elisha Jacobs · Answer 1

The crest of the wave has traveled 415 cm in 11.7s. then the crest should have travelled 415/11.7 cm in one second i. e. 35.47cm. Then the crest should have travelled 26*35.47 cm in 26 seconds i. e. 922.2cm which has 46 vibrations in it.

so for length of each vibration (Wavelength) is 20 cm
