Question

what do you mean by glass prism

Answer 1

hey dear friend!!!
 a transparent glass or plastic object that usually has three sides and that separates the light that passes through it into different colors.
i think it may help u dear!!+_+

Answer 2

In optics, a prism is an object capable of refracting, reflecting and decomposing light in the colors of the rainbow. Generally, these objects have the shape of a triangular prism, hence their name. In geometry, a prism is a polyhedron limited by two equal and parallel polygons called bases, and several parallelograms called side faces.

♦ Snell's Law in prisms

According to Snell's law, when light passes from the air to the prism glass, its speed decreases, diverting its trajectory and forming an angle with respect to the interface. As a result, light is reflected and / or refracted. The angle of incidence of the beam of light, and the refractive indexes of the prism and the air determine the amount of light that will be reflected, the amount that will be refracted or if either of the two will happen exclusively.
♦ Types of Prisms

Reflective prisms are those that only reflect light. As they are easier to process than mirrors, they are used in optical instruments such as binoculars, monoculars and others.

Dispersive prisms are used to decompose light in the spectrum of the rainbow, because the refractive index depends on the wavelength (see dispersion); The white light entering the prism is a mixture of different wavelengths and each one deviates differently. The blue light is decreased at a lower speed than the red light.

The polarizing prisms separate each light beam into components of variant polarization.

♦ Use in photography


The use of the refraction of light through the use of prisms (geometry) is becoming increasingly popular in creative photography, so much so that the term prisming has emerged as a photographic fashion. In this way, light rays of the different colors of the rainbow or reflections of white, bluish or orange tones are created depending on the ambient color temperature depending on the light used or the solar time. This series of reflections create a luminous climate.

Its main use is in portrait photography and artistic photography, especially in special events such as weddings.
