1) Which control on a music player or television set allows you to increase or decrease amplitude of the sound waves that come out of it?
2)Ripple tanks are used to observe two-dimensional waves. What should be the name of the amplitude control for two-dimensional waves?
3)Imagining a portable music player playing music in a large, open field. At some distance from the player, the amplitude of the sound waves diminishes to zero and the sound cannot be heard. Consider the three-dimensional space in which sound can be heard. How might you increase that space, and what is three- dimensional space called (in geometry)?
2. I don't know
3. Euclidean Space
