![]() The following two videos cover the features of sound as they propagate into a different medium, alongside other sound waves or around corners. Sound waves are millions of times longer than light waves. Wave superposition occurs when two or more sound waves are travelling through the same medium at the same time, the net displacement at any point in time, is simply the sum of the individual wave displacements. Penumbra : a region of partial shadow the source of the wave is partially obscured. R esonance is the tendency of a system to vibrate with increasing amplitudes at unique frequencies of excitation. Diffraction is the bending of sounds waves around obstacles and openings. Reflection of sound waves occurs when it strikes the surface of another medium and bounces back in some other direction, causing echoes more than 0.1 seconds after the original sound wave was heard. ![]() In this post, we conduct investigations to analyse the reflection, diffraction, resonance and superposition of sound waves, as a part of the Prelim Physics course under the module Waves and Thermodynamics and sub-part Sound Waves. What is reflection, diffraction, resonance and superposition in term of sound waves? Latent Heat Involved in a Change of State.When a light wave or a sound wave encounters. Both light and sound transfer energy through waves. Relationship between the Change in Temperature of an Object and its Specific Heat Capacity (Q = mc△T) Diffraction is the bending and spreading out of light or sound waves around an object. ![]()
