What are the amplitude, wavelength, frequency, and phase constant of the traveling wave in FIGURE Q16.7?
The string in FIGURE P16.60 has linear density . Find an expression in terms of M, , and for the speed of waves on the string.
A bat locates insects by emitting ultrasonic “chirps” and then listening for echoes from the bugs. Suppose a bat chirp has a frequency of 25 kHz. How fast would the bat have to fly, and in what direction, for you to just barely be able to hear the chirp at 20 kHz?
The displacement of a wave traveling in the positive x-direction
is , where x is in m and t is in s.
What are the (a) frequency, (b) wavelength, and (c) speed of this wave?
A light wave has a 670 nm wavelength in air. Its wavelength in a transparent solid is 420 nm. a. What is the speed of light in this solid? b. What is the light’s frequency in the solid?
