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

=>
