How is light different than mechanical waves in terms of their propagation and behavior?

Light waves and mechanical waves differ in their propagation and behavior. Light waves are electromagnetic waves that can travel through a vacuum, while mechanical waves require a medium, such as air or water, to propagate. Light waves also travel at the speed of light, while mechanical waves travel at varying speeds depending on the medium. Additionally, light waves exhibit properties such as interference and diffraction, which are not typically seen in mechanical waves.
