Hi I've been told to draw a graph for a progressive wave, using displacement on the y-axis, and distance from source of disturbance on the x-axis.
I have drawn one for displacement against time, but not sure how to do one for this.
I know that all the points on progressive waves have same...
Hi I had a similar question, which I posted at the the thread 'internal resistance graph'. It was basically why are V are I inversely proportional in this graph, but proportional in the graph of an ohmic conductor?
If one slit is used instead of 2 in a diffraction experiment, how does light intensity vary?
I think.. Central fringe brighter, symmetrical fringes either side of central fringe, central maximum twice the width of side fringes..
But I'm not sure why?
Also, using diffraction gratings –...
When taking internal resistance into account, voltage/current graph has negative gradient (i.e. internal resistance).?
My thoughts...
Because for ohmic resistors, graph has a positive gradient. Why does one say that when V=0, Current = max, whilst the other says that when V=0, Current = 0?
