Question

Sound exits a diffraction horn loudspeaker through a rectangular opening like a small doorway. Such a loudspeaker is mounted outside on a pole. In winter, when the temperature is 273 K, the diffraction angle $\theta$ has a value of $15.0^{\circ} .$ What is the diffraction angle for the same sound on a summer day when the temperature is 311 $k ?$

Step 1

Step 1: Use the formula $\sin(\theta) = \frac{\lambda}{D} = \frac{V}{f \cdot v_s}$ where $V = \sqrt{\frac{\gamma k T}{M}}$ for both winter and summer conditions. Show more…
