Akshay Patel 4/2/11 Period 10 Honors Physics Lab – Double Slit Experiment Objective: To determine the wavelength of light and the relationship between wavelength and color. Conclusion: In this lab, we found the wavelength of light using what we know about Young’s double slit experiment and the data we found in the lab. In this lab, we set up a optic bench with a light source, diffraction plate, diffraction scale, ray table base, slit mask, component color filters. We used the red and blue color filters and look through the window of the diffraction plate to see the number of fringes per centimeter. Each person of my group looked twice through the plate. I decide to use the mode of each set of data collected for each number. I used the equation d sin θ =m λ and y= λ Lm/d. We know the values of L, which is the length of the light source to the diffraction plate, d that is the distance of the slits from each other, m that is the number of fringes, y that is 1 cm since we look at the number of fringes per cm.
