Textbook Question
Chapter 15, Problem 85MSPP
Some bats have specially shaped noses that focus ultrasound echolocation pulses in the forward direction. Why is this useful?
A. Increasing intensity reduces the time delay for a reflected pulse.
B. The energy of the pulse is concentrated in a smaller area, so the intensity is larger; reflected pulses will have a larger intensity as well.
C. Increasing intensity allows the bat to use a lower frequency and still have the same spatial resolution.

For diagnosis, short pulses of ultrasound are passed through the patients body. An echo reflected from a structure of interest is recorded, and the distance to the structure can be determined from the time delay for the echos return. To reveal detail, the wavelength of the reflected ultrasound must be small compared to the size of the object reflecting the wave. The speed of ultrasound in human tissue is about 1 500 m/s (nearly the same as the speed of sound in water). (a) What is the wavelength of ultrasound with a frequency of 2.40 MHz?
