The objective of this research is to compare the differences in light speed in air and glass. However, the results show that light travels at the same speed in both air and glass. The authors intend to establish an accurate scientific understanding of the current world. Materials and Methods: Laser, glass plate and small and big spherical objects were used in the study. Shine laser on near and far objects and observe to verify: Whether all the laser rays are lighted up or cut off at the same time and explain why same light speed during reflection, refraction, diffusion and dispersion. Shine laser on small and big spherical objects and observe the circular object’s shadow to verify: Whether Fresnel spot is due to circumferential diffusion or diffraction. Shine laser in air and glass at the same time and compare the reflections to verify: Whether light travels the same speed for both mediums. Results: Method a: Not all the laser rays are always lighted up and cut off at the same time. Different colors of light travel at the same light speed. Method b: The Fresnel spot is due to circumferential diffusion only. Method c: The correct time frames from in air and in glass prove same light speed for both mediums. Conclusion: The experiments conclude that light speed remains the same regardless of types of non-opaque mediums or types of lights.]]> https://scialert.net/abstract/?doi=crpaj.2024.8.20 10 June, 2026
