Question

Two harmonic waves are described by

What is the wavelength of the resultant wave?
A)3 m 
B)2 m 
C)1 m 
D)4 m 
E)6 m

Quizplus · Accepted Answer

The wavelengths of the two waves are 2 m and 1 m, respectively. The resultant wave is found by adding the two waves, which yields a wave with a wavelength of the LCM of 2 and 1, which is 2 m. Therefore, the answer is (C) 1 m.
