Abstract:
The puropse of this paper is to determine the wavelength of green laser light by using DVD disc as reflection grating. This experiment has been done by using available facilities from Physics Department Laboratory in Myingyan Degree College. The measured value for the wavelength of green laser light used in this experiment was found to be 544.3 mm. The measured wavelength agrees with the wavelength of green light with the error of 2.3%.
