To measure its light-absorbing properties, beams of monochromatic light from two different lasers are shined through the glass. One laser emits red light with a wavelength of 630 nm, while the other emits blue light with a wavelength of 460 nm. What is the frequency of the light emitted (in Hz) from each laser? red ? Hz blue ? Hz (b) The glass absorbs 73.0% of the energy of the blue light; that is, the intensity of the blue light just after exiting the glass is 27.0% of the intensity just before entering. (The sheet of glass is thin and the laser beam narrow, so the intensity change is not due to any widening of the beam.)

- You have decided to build your own speaker system for your home entertainment system. The system will consist of two loudspeakers: a large woofer, to which you want to send low audio frequencies (bass), and a small tweeter, which should receive high audio frequencies (treble). To separate the high and low frequencies of the audio signal, you build the crossover network shown in Figure P32.45. The input voltage is the audio output of the amplifier in your system, shown in the figure as an AC source. You have two outputs as shown: one across the resistor and one across the capacitor. (a) Across which element should you connect the woofer? (b) Across which element should you connect the tweeter? (c) To choose the appropriate values of R and C, you need to determine an expression for the ratio of the output voltage to the input voltage as a function of angular frequency for the resistor as an output. (d) You need to determine a similar expression for the ratio of the output voltage to the input voltage as a function of angular frequency for the capacitor as an output. Figure P32.45arrow_forwardYou are seated on a couch equidistant between two speakers. The speakers are 2.0 m apart and you are seated 4.0 m away from the point between the speakers as shown in Figure P35.4. Both speakers play an A note (a constant frequency of 440 Hz) in phase and at the same volume. As you move left and right along the couch, you notice that the volume alternates between minimum and maximum due to interference effects. Assume the speed of sound is 343 m/s. a. When you are seated at the center of the couch, is the sound a maximum or minimum in volume? b. If you slide along the couch to the left or right, approximately how far do you need to move until you reach the next location that has the same volume? (Hint: You may wish to obtain an exact expression and then use a spreadsheet or trial and error to find an approximate solution.)

- A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.arrow_forwardA student holds an inexpensive sonic range finder and uses the range finder to find the distance to the wall. The sonic range finder emits a sound wave. The sound wave reflects off the wall and returns to the range finder. The round trip takes 0.012 s. The range finder was calibrated for use at room temperature T=20C , but the temperature in the room is actually T=23C . Assuming that the timing mechanism is perfect, what percentage of error can the student expect due to the calibration?arrow_forwardA train sounds its horn as it approaches an intersection. The horn can just be heard at a level of 50 dB by an observer 10 km away, (a) What is the average power generated by the horn? (b) What intensity level of the horn's sound is observed by someone waiting at an intersection 50 in from (lie train?
