Compute the each part of following question given below:
Question: A single, monochromatic light source is shined through an etched, flat prism with a slit separation of 0.025mm. The resulting interference pattern is viewed on a screen 1.25m away. The third maximum is found to be 6.60cm from the central maximum.
Part I: What is the wavelength of the light?
Part II: How far away from the central maximum are the first and second maxima?
If possible just a brief explanation how you got the answer?
