Being able to behave as a wave, light can be dispersed from its source point using slit/s. This is called single slit diffraction. Using this ability, the wavelength of a certain light source, like laser, can be determined. This is through the working equation: 𝑎𝑠𝑖𝑛𝜃=𝑚𝜆. Through the CCD (charge-coupled device), the diffraction of the light was seen and using the Vision Assistant Program, the order for the destructive interference was known. The manipulated variable in this research was the usage of different slit widths (0.04 mm, 0.08 mm, and 0.16 mm). It was seen from the experiment that the wavelength is approximately close to the actual one. Even though different slit widths were utilized in the study, the wavelength remained close to the original value. Data analysis was done after the conduct of the study and it was concluded that the smaller the value of the slit width, it became difficult to measure the value of the wavelength due to the larger distance between the destructive interferences but it has a much more precise measurement, which was seen in the calculations of the percentage error.
