John William Strutt, Lord Rayleigh (1842-1919), invented an improved foghorn. To warn ships of a coastline, a foghorn should radiate sound in a wide horizontal sheet over die oceans surface. It should not waste energy by broadcasting sound upward or downward. Rayleighs foghorn trumpet is shown in two possible configurations. horizontal and vertical, in Figure CQ38.10. Which is the correct orientation? Decide whether the long dimension of the rectangular opening should be horizontal or vertical and argue for your decision.
