Assuming that audible sound has a maximum frequency of 10000 Hz, what is the maximum number of radio channels that can fit onto the FM radio band without overlap? (The frequency range of FM is 88 MHz to 108 MHz).
Solutions
Expert Solution
frequency of massage signal , fm = 10000 Hz
band width of massage signal W = 2 fm =20000 Hz
FM band width , WFM = 108 - 88 = 20 MHz

3. (a) The range of audible frequencies of sound in air,
assuming sufficient amplitude, is from about 20 Hz to 20, 000 Hz.
What is the range of audible wavelengths? Take the speed of sound
in still air to be v = 344m/s.
(b) Sound is detected when the eardrum is caused to
vibrate. The diameter of the eardrum is about 10 mm. Suppose a
person whispers into your ear with an intensity, I = 10−8 W/m2 =
E/(At), where...

Sound with a frequency of 1250 Hz leaves a room through a doorway
with a width of 1.05 m.
At what minimum angle relative to the centerline perpendicular to
the doorway will someone outside the room hear no sound? Use 344
m/s for the speed of sound in air and assume that the source and
listener are both far enough from the doorway for Fraunhofer
diffraction to apply. You can ignore effects of reflections.

A tuning fork generates sound waves with a frequency of 230 Hz.
The waves travel in opposite directions along a hallway, are
reflected by walls, and return. The hallway is46.0 m long and the
tuning fork is located 14.0 m from one end. What is the phase
difference between the reflected waves when they meet at the tuning
fork? The speed of sound in air is 343 m/s. (Ans in degrees)

Question 1: SOUND
a) A bystander hears a siren vary in frequency from 570 Hz to
398 Hz as a fire truck approaches, passes by, and moves away on a
straight street. What is the speed of the truck? (Take the speed of
sound in air to be 343 m/s.) By how many decibels do you reduce the
sound intensity level due to a source of sound if you triple your
distance from it? Assume that the waves expand spherically....
