Topic: Waves Aim: How do waves behave? Do Now: Take out last night’s HW. HW: Ditto – Forms of Energy (in your Energy Notes packet) Energy Castle Learning due tomorrow!!!
A Identify each part of a wave labeled in the diagram above. B C D
1.Which wave has the greatest amplitude? 2.Which wave has the greater wavelength? 3.Which wave has the greater frequency?
What happens if a wave hits a barrier? 1. Energy may be absorbed. 2. It can bounce off. 3. It can pass through it.
Have you ever noticed that objects underwater seem closer to the surface than they really are? The light waves reflected from the swimmer’s foot are refracted away from the normal and enter your eyes.
AM radio waves have longer wavelengths than FM radio waves do. Because of their longer wavelengths, AM radio waves diffract around obstacles like buildings and mountains. As a result, AM radio reception is often better than FM reception around tall buildings and natural barriers such as hills.
