Six different experiments on refraction, reflection, diffraction, and interference were performed. The helium-neon laser has provided monochromatic, coherent, intense, and collimated light in the study of the fundamental optical phenomena by experimentation. With the use of the helium-neon laser light, the index of refraction of glass prisms and liquids were measured with high precision and accuracy. Its wavelength was also determined. The light from the helium-neon laser verified the laws of reflection accurately. Diffraction and interference patterns, as well as the intensity distribution of single, double and multiple slits were studied qualitatively and measured quantitatively. From the experiments performed, it was concluded that the characteristic properties of helium-neon laser as a source of light minimized sources of error to a high degree. It has also provided accurate and precise means of measuring physical quantities especially in optics. 1974-01-01T08:00:00Z text https://animorepository.dlsu.edu.ph/etd_masteral/278 Master's Theses English Animo Repository Helium-neon lasers Physics |
