- True or false: the response of the ear to the sound intensity is closer to being linear then logarithmic?
- True or false: every 10 dB the sound intensity doubles?
- The sound intensity I is measured as sound power P per unit area A in Watts per square meter (W/m2).
- It is possible to focus light but impossible to focus sound
- When two (or more) waves travel simultaneously in the same medium, the total disturbance in the medium at each point is the vector sum of the individual disturbances produced by each wave.
- how many joules of work done equals a force of how many newtons equals how far an object moves
- The - is the most important source of EM radiation.Other sources of EM waves depend on -
