What Is The Period Of A Wave False

Decent Essays

20.01
“The particles in the pulse travel from one place to another”, it’s incorrect because the definition of wave is transferring energy without transferring any mass. So particles don’t travel in pulse.

20.03
“The wave continues to travel for 0.20s before stopping”. Its wrong since period is the time for one complete vibration and it doesn’t relate to the time that wave stops.
“The wavelength is 0.20s”. It’s wrong, because 0.20s is the wave’s period not its wavelength. Wavelength is length of one complete vibration and its unit is (m).

20.04
“The wave disturbance travels 300m for each wavelength”. Not correct, because wave speed is the speed of wavelength over its period and it doesn’t relate to wave disturbance. …show more content…

Because, wave is transfer of energy not a particle. Wave speed is the speed of one particular distance in wave.

24.05
“The period of the wave is 4.0m”, is wrong. Wavelength is the length of one period and its different with period. The unit of period is (s).
“The wave continues to travel for 4.0m before stopping”, is wrong. The wavelength doesn’t relate to the point that wave will
