1. A source moving with a speed 37 m/s, emits a sound wave with a frequency f = 377 Hz. Determine the frequency detected by a stationary observer if the speed of sound is v = 343 m/s and the source is moving towards the observer. 2.A stationary source, emits a sound wave with a frequency f = 428 Hz. Determine the frequency detected by an observer moving towards the source with a speed v = 43 m/s, if the...

Question: To demonstrate the Doppler effect, your lecturer puts a tone generator playing a 564 Hz tone in a ball tied to a rope and swings it around. As it swings, you hear a maximum frequency of 578 Hz from your seat in the middle of the large lecture hall. Assume the speed of sound through the air is 336 m/s. Part 1) What speed is the ball moving at? v = 8.14 m/s Your last answer was interpreted as...

A speaker and microphone are attached to a cart moving toward a wall at speed LaTeX: v v m/s. The speaker sends out a constant tone, 236 Hz. The sound reflects off the wall and the reflected wave is detected by the microphone to have frequency 277 Hz. Taking the speed of sound in air to be 343.9 m/s, with what speed does the cart approach the wall? Give your answer to the nearest 0.1 m/s.

You are listening to a speaker on a tripod in a room with a nice
smooth marble floor, as shown in the figure below. The speaker
emits sound of wavelength (lambda). The speaker s and your ear e
are the same distanceh above the floor. Your ear and the speaker
are a distance d = 4 h away from one another.
Not only does your ear sense the sound wave moving along path 1,
but your ear also senses the...

Please help with #3 ( a multi-part question)
2. When a 100 H tor is used to generate a sinusoidal wave on a certain string the z oscilla wavelength is 10 cm. When the tension in the string is doubled the generator produces a wave with a frequency and wavelength?

The drawing shows three situations - A, B, and C - in which an observer and a source of electromagnetic waves are moving along the same line. In each case the source emits a wave that has a frequency of 4.57 x 1014 Hz. The arrows in each situation denote velocity vectors of the observer and source relative to the ground and have the magnitudes indicated (v or 2v), where the speed vis 1.6 X 10° m/s. Calculate the observed...
