Nicholas Charles Miller - PHY183, Spring 2010 - Physics for Scientists and Engineers I 1 Homework Set 12 Due date: Sun May 2 23:59:00 2010 The range of human hearing extends from approximately 20 Hz to 20 000 Hz. Find the wavelengths of these extremes at a temperature of 30 C What is the longest audible wavelength? Tries 0/99 What is the shortest audible wavelength? Tries 0/99 A piano emits sound waves with frequencies that range from a low of about 28 Hz to a high of about 4,200 Hz. The speed of sound in air is approximately 343 m/s. What is the longest wavelength of sound produced by a piano? Tries 0/99 What is the shortest wavelength of sound produced by a piano? Tries 0/99 **The ship in the ±gure above travels along a straight line parallel to the shore and is a distance Y=550 m from the shore. The ship’s radio receives simultaneous signals of the same frequency from antennas at points A and B which are separated by X=820 m. The signals interfere constructively at point C, which is equidistant from A and B. The signal goes through the ±rst minimum at point D which is even with B. Determine the wavelength of the radio waves. Tries 0/99
