(7) The wavelength of a sound emitted by a foghorn at a Pacific harbor is 3.68 m on a warm summer day, when the air temperature is 36°C. (a) What's the sound frequency? (b) How many seconds will the first wavefront of sound take to reach a boat at sea that is a distance of 0.82 miles from the foghorn? (c) How many seconds would the same wavefront take on a cold winter day, when air temperature is -16°C?
