Question

Gustave has three wood panels. Each panel has a small aperture as listed below: Panel A: radius = 30 cm Panel B: radius = 50cm Panel C = 20 cm He also has three speakers, each speaker gives the sound frequency listed below: Speaker D : 4000 Hz Speaker E : 8000 Hz Speaker F : 1500 Hz Determine which panel and speaker combination will result in the greatest diffraction angle for sound once the sound diffracts through the hole. Determine which panel and speaker combination will result in the smallest diffraction angle for sound once the sound diffracts through the aperture. Superposition/constructive and destructive interference of waves. Below are two waves, A and B. Draw as carefully as possible as possible the resulting third wave. On at least one position on the resulting wave, label a constructive event. And on your resulting third wave, label a destructive event.

Explanation / Answer

PART 1)

Panel B and speaker F will show maximum diffraction as we can see that its frequency is least as welll as area is maximum

so it will give maximum diffraction here

PART 2)

Panel A and Speaker E will show least difrraction as its area is maximum and hense diffract for that frequency is least
