I have just read about dispersion of light by a prism and the thing which i donnot understand is that WHY does the light bend at all? Through prisms and slabs?
I came to know that red light has the longest wavelength and then i read a formula, Energy is inversely proportional to wavelength. That means that red light contains the least energy . And it bends the least. WHY? Why does it not bend as much as violet ( i know they have more energy but what makes them bend ? )
( P.S - try not to explain using Snell’s laws )
