Laser light passing through a Diffraction gradient,a CD

Investigation

How the distance of the CD affects

The distance of the 1st maxima

Hypothesis

Further the DC will be from the wall, with the function of the diffraction grating, more the maxima will increase proportionally distant from the focus point.

Which resulted correct observing the graph trend

Those will interfere with each other and, the places where this occurs, dots will represent the interference

The dots are called as maximas of the diffraction due to the their color intensity.
