Question: Rick creates a wave with 10N of force, and he compares it to a normal wave with 100N of force. The wave with farther apart particles has _____ of force.
Answer: 10N
answer:
Places where particles of a medium crowd closer together are called compressions, and places where the particles spread farther apart are called rarefactions. The more energy the wave has, the closer together the particles are in compressions and the farther apart they are in rarefactions.
