WAVES

Question 1

What is a transverse wave?

Answer 1

Oscillations are perpendicular to the direction of energy transfer. E.g EM waves.

Question 2

What is a longitudinal wave?

Answer 2

Oscillations parallel to the direction of energy transfer. E.g Sound waves.

Question 3

What are EM waves?

Answer 3

Vibrating electric field generates a vibrating magnetic field, which also generates a vibrating electric field further away.
-Can travel through space without the need of a substance to go through.

Question 4
