Sound waves are mechanical waves that require a medium to travel through, such as air, water, or a solid substance. They propagate by the vibration of particles in the medium.
Light waves, on the other hand, are electromagnetic waves that can travel through a vacuum as well as through a medium. They propagate through the oscillation of electric and magnetic fields and do not require a medium to travel through.
Sound waves are slower than light waves and have a lower frequency and higher wavelength. Sound waves also exhibit characteristics such as reflection, refraction, and diffraction, while light waves primarily undergo reflection and refraction. Additionally, the human auditory system is capable of detecting sound waves, while the human visual system is capable of detecting light waves.
How are soundwave different from light waves?
