Question

Mechanical vs Electromagnetic Waves
One way to classify waves is on the basis of their ability or inability to transmit energy through a vacuum. Classifying waves like this leads to two categories: electromagnetic waves and mechanical waves.




Question 1

Question 2
PART B
A vibration of an electric charge.
Transmits energy from the Sun to Earth
A wave which has both an electric and a magnetic component
