What is constructive interference?
The amount of energy a sound wave carries per second through a unit area.
What is intensity?
Monica was using different colored pieces of clear plastic for an art project. Her little brother came and scattered the plastic all over the photograph of the image she was using as a guide. As she was cleaning up, she noticed that the image appeared differently behind certain colors of plastic. Why was this?
All colors except the one that matches the plastic can pass through, leaving that color black.
