You get to find out how waves can be reflected or refracted. Perform experiments on refraction in order to demonstrate Snells law.
After completing this tutorial, you will be able to complete the following:
What happens to sound waves in a room?
~ Sound waves spread out into a room. Some of those waves are absorbed by the walls and some are reflected back into the room.
What is an echo and how is it formed?
~ An echo is a reflection of sound. When a sound is made in front of a high obstacle, it travels a certain distance, reflects from the obstacle, and returns. We perceive this reflection as a second sound a few moments later.
