Particles in Waves - Sound | Learn with BYJU'S

What is sound? Why can we hear sound and not see it? Is sound same for all the animals?
We at Byju's Classes strongly believe that a spirit of learning and understanding can only be inculcated when the student is curious, and that curiosity can be brought about by creative and effective teaching. It is this approach that makes our lectures so successful and gives our students an edge over their counterparts.
