Answer:
The wavelength is
Explanation:
From the question we are told that
The wavelength of the red laser is
The spacing between the fringe is
The spacing between the fringe for smaller laser point is
Generally the spacing between the fringe is mathematically represented as
Here is the distance to the screen
and d is the distance of the slit separation
Now for both laser red light light and small laser point D and d are same for this experiment
So
=>
Where is the wavelength produced by the small laser pointer
So
=>
