Asked by Manie
3. What happens to the speed of ocean waves as they come close to shore? How can this be explained from what you've learned so far?
(this the teacher means what do the lessons have to do with this question)
4. Sound travels faster through wood than through air. Sound also travels faster through helium than through air. Using the concepts of density and rigidity, explain these observations.
Please help?!?! I only need to figure out these 2 to finish the assignment! Thank you!!
