Mechanical waves require a medium like air, water, or a rope to travel through. On the other hand, light waves, which are a type of electromagnetic wave, don't need a medium. They can travel through the vacuum of space. Wave properties can also be represented as the brightness and color of light.

They have key characteristics like period, wavelength, and frequency. The speed of a wave can be affected by its type and the medium it travels through. There are two main types of waves: mechanical, which need a medium to travel through, and electromagnetic, which can travel through a vacuum.
