Oscillations ... WebDevelop models based on experimental evidence that illustrate the phenomena of reflection, refraction, interference, and diffraction. Obtain, evaluate, and communicate information to support the claim that electromagnetic (light) waves behave differently than mechanical (sound) waves.

WebA sound wave can be controlled in one of three different ways – it can be reflected, diffused or absorbed. Each of these reactions will depend entirely on the nature and composition of the material it comes into contact with, and each … WebThe fact that you can hear sounds around corners and around barriers involves both diffraction and reflection of sound. Diffraction in such cases helps the sound to "bend around" the obstacles. The fact that diffraction is more pronounced with longer …

WebMar 18, 2024 · Therefore, sound waves can be diffracted. Note: According to the Huygen’s each point on a wave acts as a source and hence is called secondary wavelets. The corners or opening through which diffraction takes place also acts as a source. The source of waves must be coherent.
