**Problem #19:** You and a friend are watching fireworks that are launching from Grant Park. You are standing right in front of 624 S. Michigan Building (150 m from the launch area) and your friend is across campus at the Film Department (700 m from the launch area). The sound intensity at the Film Department is 0.2 W/m². What is the sound intensity at your location, and how much power is the firework emitting?

We know that the intensity of a sound source is inversely proportional to the distance from the…

1. (a) What is the intensity in W/m² of a laser beam used to burn away cancerous tissue that, when 90.0% absorbed, puts 650 J of energy into a circular spot 1.9 mm in diameter in 4 s? Hint: The laser is a collimated beam of light and does not produce a spherical wave. W/m² (b) Reflect on how this intensity compares to the average intensity of sunlight (about 1W/m²) and the implications that would have if the laser beam entered your eye. Note how your answer depends on the time duration of the exposure. The intensity of a laser is about be very damaging if they enter your eye. ✓times that of the sun, so clearly lasers can
An intensity detector can be moved along a straight track. a source of spherical waves is placed at one end of the track. When the detector is 2 m away from the source, it measures an intensity of 80 W/m2. What distance do we need to move the detector from that position to get a measurement 13 dB lower? Answer: 6.95m
Two identical guitar strings are prepared such that they have the same length (0.68) and are under the same amount of tension. The first string is plucked at one location, primarily exciting the first harmonic. The other string is plucked in a different location, primarily exciting the fourth harmonic. The resulting sounds give rise to a beat frequency of 324Hz. What is the wave propagation speed on the guitar strings? wave propagation speed: m/s
A row of seats is parallel to a stage at a distance of 8.4 m from it. At the center and front of the stage is a diffraction horn loudspeaker. This speaker sends out its sound through an opening that is like a small doorway with a width D of 0.074 m. The speaker is playing a tone that has a frequency of 2.00 104 Hz. The speed of sound is 343 m/s. What is the distance between two seats, located near the center of the row, at which the tone cannot be heard?
Two loudspeakers emit sound waves of the same frequency along the x-axis. The amplitude of each wave is a. The sound intensity is minimum where speaker 2 is 10cm behind speaker 1. The intensity increases as speaker 2 is moved forward and first reaches minimum, with amplitude 2a, when it is 30cm in front of speaker 1. a. what is the wavelength of the sound
The figure below shows wave fronts of sound waves from the siren of a police car. Two people on both side of the car are running at 5 m/s to the left. The frequency of the siren is 400 Hz. The person on the left observes a frequency of 388.7 Hz. Speed of sound in air is 340 m/s. a) How fast is the policy car travelling? b) What is the frequency observed by the person on the right? c) What is the wavelength observed by the person on the righ? R

A listener is standing on a ground that is non-absorbing. Situated at a distance from the listener are two sound sources such that: source A has a sound power of 5 W and 15 m from the listener and source B has a power of 15 W and 25 m from the listener. What is the sound pressure level the listener would hear
