SOUND SIMULATION:
Answer the following questions about the sound simulation: The sound passing through the horn appears to be causing patterns of bright and dark ripples. In terms of light in the real world, what do the ripples mean? You may find the "particle" view helpful in answering this question. Looking at the graph of pressure as a function of time, do the areas of high pressure correspond to the brightest ripples, darkest ripples, or the area between them? Decrease the amplitude of the sound. What happens to the colors? What would happen in the real world? Increase the frequency of the sound. What happens to the ripple pattern? What would happen in the real world? Compare the light and sound simulations. Are there any substantial differences in the interference patterns?Explanation / Answer
1. Bright and Dark ripples mean Waxing and waning of Sound
2.Yes
3. No Change in colors
4.Number of ripples will increase with Frequency
