Unformatted text preview: Exam Phys 2Ca, Fall 07 Name__Mechanical waves_________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. 1) What of the following is a WRONG statement A) Longer waves on the surface of deep water propagate faster than shorter waves B) If an upward and downward pulse, otherwise identical in shape, are propagating in opposite directions along a stretched string, at the instant they overlap completely and the displacement is zero everywhere, the whole energy of the two pulses is stored as potential energy. C) A non- harmonic wave propagating on the sufrace of deep water is likely to change this shape due to wave dispersion. D) There are waves that cannot be classified as either transverse nor longitudinal. 2) What of the following is a WRONG statement A) A propagating pulse has an amplitude but does not have a frequency. B) To tune the frequency of a string to the frequency of a tuning fork (that produces a sound of a highly reproducible frequency), one needs to increase the period of the beats produced by interference of the...
