A glass prism is a transparent object having two triangular ends and three rectangular sides. The refraction of light in glass prism is different from a glass slab. This is because in glass prism, the ...

If the light rays are travelling from one medium to another they change their direction at the boundary between two mediums. When the light rays either bend or change their direction while passing ...

The origin of a rainbow can be answered by almost everyone. We learn the physics behind a rainbow very early in our lives, but the phenomenon responsible for it does not linger in the minds of ...

For the first time, physicists have devised a way to make visible light travel in the opposite direction that it normally bends when passing from one material to another, like from air through water ...

IN such elementary text-books on geometrical optics as I have consulted it has always seemed to me that the writers have found a difficulty in presenting a precise direct proof of the theorem that ...

PROVIDENCE, R.I., June 10, 2025 /PRNewswire/ -- Meller Optics, Inc. has introduced custom fabricated sapphire prisms that bend, split, or reflect light but are resistant to scratching, and transmit ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

There has been a surprise discovery of ‘significant’ refraction of gamma rays which opens the door to nuclear photonics and the use of high energetic light beams to investigate the atomic nucleus.
