WebMar 31, 2024 · When a wave travels from one medium to another then bending of the wave is called refraction of the wave. Explanation: As the sound wave is a longitudinal wave that can’t be polarized. So option 4 is correct. The sound wave can be diffracted at the corners. So option 3 is not correct. WebApr 13, 2024 · Sound waves can also be reflected, refracted, or diffracted, depending on the properties of the medium. The human ear is capable of detecting sounds within a certain range of frequencies, from 20 Hz to 20,000 Hz. Sounds that are above this range are called ultrasonic, while sounds below this range are called infrasonic. ...

WebAnswer (1 of 2): Yes. It varies a bit by frequency – but works somewhat like the ripples when you toss a stone into a pond. A guy named Jonathan Sheaffer has some ... 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.

WebOne feature of waves, known as diffraction, is that they can bend around corners or obstacles. The degree of diffraction increases with increasing wavelength. Furthermore, the size of the obstacle (or opening it is passing through) must be comparable to or smaller than the wavelength of the waves.
