Set the slit width to 500 NM and slit separation to 1500 NM. Record your slit separation din Table 1.
B)Press the green button on the light generator and generate an interference pattern on the screen.
C)Pull the measuring tape tool out of the box in the upper right and use it to measure L, the distance between the slits and the screen. Then measure the distance from the center of the central bright spot to the center of one of the 1storder bright spots. Record these values in Table 1.
D)Calculate the wavelength of the light λusing the diffraction formula derived in the Background section. Record this value in Table 1.
E)Pause the simulation and use the measuring tape tool to measure the wavelength directly. Record this value in Table 1.
F)Calculate the %-error between your calculated and measured values, and record this value in Table 1.
G)Adjust the frequency of light and repeat steps B-F.
