FAQs

Question: What is simple harmonic motion?
Answer: Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement from the equilibrium position.

Question: How do waves transfer energy?
Answer: Waves transfer energy through the oscillation of particles in the medium, allowing energy to move from one point to another without the permanent displacement of the medium itself.
