l luple Multiple-Choice Practice Test.pdf (page 4 of 9) RAND ANYON UNIVERSITY Topic 7, esti 10: A small vibrating objects moves across the surface of a tankof water producing the wave fronts shown in the figure below. The wave fronts move with speed v. The object is traveling in what direction and with what speed relative to the speed of the waves? A. To the right with a speed greater than v B. To the left with a speed greater than v c. To the right with a speed equal tov D. To the left with a speed less than v E. To the right with a speed less than v Topic 7 uestion 11

Explanation / Answer

E)to the right with a speed less than v.

because, wavelength of the waves in right side less than wavelength of the waves in left side.

so, the vibrating object is travelleing towards right.

and the speed of the object is less than v.

because, the waves are not overlaped.
