Some terms related to prism are: Angle of deviation (∠ẟ): The difference in the initial and final direction of propagation of light rays... View Article
Dispersion of light can be defined as spreading of light into its full spectrum of different wavelengths due to passing of white light through a... View Article
If the light rays are travelling from a denser to a rarer medium, there might be an incident angle when the refracted angle becomes 90 , this... View Article
In this case, we take the glass slab around a rarer medium like air. Now, if it is denser medium, the rays of light would move towards the... View Article
The change of refractive index effects different factors of light in different waves. The major factors which change due to change in the... View Article
Refractive index can be explained using a simple analogy. Refractive index can be said as the density for light or can be said as optical... View Article
Whenever a light ray interacts with a surface or a medium, three outcomes are possible. These are reflection, absorption and refraction. The... View Article
