What is caused by bending across obstacles in sound waves? Correct Answer Diffraction

Diffraction causes bending across obstacles. The bending of waves around small obstacles and the spreading out of waves is called diffraction. As the wavelength of sound is much larger than that of the light, bending is quite obvious around small obstacles like casing of a microphone or a loudspeaker.

In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: As the source continues to vibrate the medium, the vibrations propagate away from the source at the speed of sound, thus forming the sound wave. B: The sound source creates vibrations in the surrounding medium.  C: The sound waves are generated by a sound source, such as the vibrating diaphragm of a stereo speaker. D: Sound can propagate through a medium such as air, water, and solids as longitudinal waves and also as a transverse wave in solids.
