Waves and Energy Practice

Electromagnetic waves are different from mechanical waves because

• they are capable of transferring energy through a vacuum.

• electromagnetic waves only travel through a medium

• electromagnetic waves travel slower than mechanical waves

• electromagnetic waves are not emitted from the Sun
