A = ii. Maximum intensity of sound is heard at point O. The loudspeakers are 0.40 m apart and the distance OP is 2.4 m. P is the position of the first minimum. Calculate the distance D from the loudspeakers to the line OQ. Assume that the equation used for the interference of light from a double-slit also applies for the sound from these two loudspeakers. DE............Um (e). i. Explain the term intensity
