1. Fill a sink or bath tub with water.
2. Practice tapping the cork on the surface of the water (about 3 _times per second works well) to create evenly spaced waves.
3. Tapping the water at the same frequency, move your object in a straight line in one direction in a broad, sweeping motion-not too fast, or you will have a hard _me seeing the effects!
4. As you move the object, try to observe the spacing of the waves extending in front of the object compared to the ones behind it.
5. Try a number of different speeds and tapping frequencies until you can see a spacing difference between the front and back waves.
a) It is a sort of disturbance which goes by a medium. b) Material phase is necessary for the propagation of mechanical waves. c) When a wave motion goes by a phase, molecule

Power factor improvement: The low power factor is because of the fact that most of the power loads are inductive and thus take lagging currents.
When hydrogen atom is excited, it returns to its normal unexcited (or ground state) state by emitting the energy it had absorbed previous. This energy is given out by the atom in t

The speed at which a wave propagates down a string is 300 meters per second. If the frequency of this wave is 150 Hertz, what is the wavelength of this wave? Ans: The wavel
