Prescribing Eyeglasses - Hyperopia Due this Friday, Mar 30 at 11:59 pm (EDT) Suppose you have hyperopia (you are farsighted). You can clearly focus on very distant objects, but any object which is closer than 43.7 cm from your eyes will appear blurry unless you use glasses. The purpose of glasses would be to make objects that are close to you appear to be at your near point. What would be the refractive power (in diopters - do not enter...

3. A trumpet creates a sound intensity level of 1.15*102 dB at a distance of 1.00 m. I. What is the sound intensity of a trumpet at this distance? II. What is the sound intensity of five trumpets at this distance? III. Find the sound intensity of five trumpets at the location of the first row of an audience, 8.00 m away, assuming, for simplicity, the sound energy propagates uniformly in all directions. IV. Calculate the decibel level of the...

You stand 5 meters away from two machines. One machine operates at a sound intensity level that is 50 dB at your location. The other machine operates at a sound intensity level of 70 dB at your location. What sound intensity level do you hear (measure in dB) when both machines are turned on?
5. By how many decibels do you reduce the sound intensity level due to a source...
5. By how many decibels do you reduce the sound intensity level due to a source of sound if you double your distance from it? Assume that the waves expand spherically. dB 6. The sound in a classroom is 63000 times as intense as the minimum threshold of hearing. What is the intensity level of this sound in decibels? dB
