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).

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
