A skyrocket explodes at a height h = 73 m above the ground (see figure). Three observers are spaced 100 m apart, with observer A directly under the point of the explosion. Neglect the height of the observers. h 100 m (+0.02) 100 m (a) What is the ratio of sound intensities heard by observers A and B? Caution: We want the ratio of intensities (in W/m2), not the ratio of intensity levels (in dB). (b) What is the ratio of intensities heard by observers A and C?
