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.Relationship between the Change in Temperature of an Object and its Specific Heat Capacity (Q = mc△T).Relationship Between the Temperature of an Object and Kinetic Energy.Applying Equations and Relationships to Solve Questions (Refraction Index, Snell's Law, Critical Angle, Intensity of Light).Relationship Between the Inverse Square Law, the Intensity of Light and the Transfer of Energy.Practical Investigation: Phenomenon of the Dispersion of Light.Refraction and Total Internal Reflection.Practical Investigation: Formation of Images in Mirrors and Lenses.Behaviour of Standing Waves on Strings and Pipes.Reflection, Diffraction, Resonance and Superposition of Sound Waves.Relationship Between Distance and Intensity of Sound.Displacement of Air Molecules as Variations in Pressure.Practical Investigation: Pitch and Loudness of a Sound.Resonance in Mechanical Systems (Driving Frequency, Natural Frequency, Amplitude, Transfer of Energy).Reflection, Refraction, Diffraction and Wave Superposition.Graphs of Displacement as a Function of Time (Transverse and Longitudinal Waves).Practical Investigation: Transverse, Longitudinal, Mechanical and Electromagnetic Waves.Practical Investigation: Creation of Mechanical Waves.
