Mechanical/EM Waves Quiz

What is the difference between mechanical waves and electromagnetic waves?

• Mechanical waves are transverse waves, while electromagnetic waves are longitudinal waves

• Mechanical waves can travel at the speed of light, while electromagnetic waves cannot

• Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

• Mechanical waves are produced by electric charges, while electromagnetic waves are produced by vibrating objects
