1.	Which is not the property of sound wave? beat frequency, polarization, diffraction, refraction
Answer» ATION is not the property of sound WAVE. because Polarization has a wealth of other APPLICATIONS besides their use in glare-reducing sunglasses. In industry, Polaroid filters are used to perform stress analysis tests on transparent PLASTICS. As light passes through a plastic, each color of visible light is polarized with its own orientation.
