Hypothesis: Part A
If we split a laser beam by using a diffraction grating slide, then we can
verify the by applying the formula λ = ds/l.

2) Part B If we split light into its individual wavelengths using a diffraction grating,
then we can determine the by multiplying the spacing of the
gradient lines (d) times the distance to the central maxima of the color band (s)
divided by the length distance from the grating slide to the screen (l).

1.) Wavelength

2.) Number of fringes

Explanation:

1.) If we split a laser beam by using a diffraction grating slide, then we can

verify the wavelength by applying the formula λ = ds/l.

2) If we split light into its individual wavelengths using a diffraction grating,

then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).
