If equation y = A sin ( wt = kx ) , t stood for time and distance respectively obtain dimensional formula for w and k with explanation please |
|
Answer» Answer: ANGLE is dimension less quantity.So the argument (wt-kx) is a dimension less.So wt & kx are also dimension less separately ,now the dimension of time is [ T ],so dimension of w must be [1/T ] in order to make their product dimension less and with similar argument the dimension of k is [1/L] actually w is called ANGULAR FREQUENCY ,means number of full cycle in unit time and k is called propagation VECTOR and it equal to 2π/(wave length) Step-by-step explanation: It is the correct answer please Mark Me as brainleist |
