Fig. 6.1 shows eleven evenly-spaced parallel wavefronts, A to K, moving in air. Calculate the wavelength of the wave.

A16.5 m

B82.5 m

C15 m

D33 m

Explanation

The 11 wavefronts span 10 wavelengths over 165 m, so wavelength = 165/10 = 16.5 m. (15 m wrongly divides by 11; 33 m and 82.5 m divide by the wrong number of gaps.)
