1) As the width of the single-slit increases, number of maxima is increased and the distance between each is diminished.

2) The red laser has a lower intensity than the green laser.

3) The single-slit produces fewer separate maxima that are more elongated and have a greater distance between each one. The double-slit produces many distinguishable maxima and the space between each is significantly diminished..

4) As the width of the single-slit increases, number of maxima is decreased and the distance between each is elongated.

5) The spacing between each maximum is smaller with the green laser than with the red laser.

6) Because the maxima are very sharp and narrow and have a greater distance between them, more so than the double-slit.

7) As the spacing increases, the spacing of the intensity pattern is smaller and there are fewer lines.

8) The distances between maxima are smaller with the green laser.

Wavelength:

$d\sin\theta=m\lambda\:\therefore\:\lambda=\frac{\:d\sin\theta}{m}$

m=1

$d=.5\times.013837\:in=.0069185\:in=.0166044\:cm$

$\theta=\tan^{-1}\left(\frac{1.5\:cm}{82\:cm}\right)=1.04797º$ º

$\lambda=\frac{\left(.0166044\:cm\right)\sin\left(1.04797\right)}{1}=3.0368\times10^{-4}\:cm$
