Dispersive power of prism vlab
WebVideo Transcript. In this video, our topic is the dispersive power of a prism. Dispersion is what we see going on in the sketch. We have a beam of light containing both red and blue light, which once it enters this prism separates out into these two different beams. In this lesson, we’ll come up with a quantitative way of describing how ... WebThis video clearly explains about measuring Dispersive power of given prism using Spectrometer.Explained by : Dr B.Ashok
