Two times.
One when the light beam crosses the air-prism interface and enters the prism and
a second time when the beam crosses the prism-air interface on its way out of the
prism.
If light is passed through a prism, it will be refracted into its component colors, creating a spectrum of colors known as a rainbow. This occurs because different colors of light have different wavelengths, leading to their separation as they pass through the prism.
The red light is refracted as it passes through a prism. The different colors of light are refracted at slightly different angles due to their differing wavelengths, causing them to separate and create a rainbow effect.
The violet colour will be refracted the most, it has a shorter wave length and a higher frequency. The red light will be refracted the least, with its longer wave length and lower frequency.
Violet light is refracted the most by a prism, followed by blue, green, yellow, orange, and red. This dispersion of light creates a rainbow effect when white light passes through a prism.
Violet light is refracted through the largest angle when white light passes through a glass prism because it has the shortest wavelength of all the colors in the visible spectrum.

Violet light is refracted through the largest angle when white light passes through a glass prism because it has the shortest wavelength of all the colors in the visible spectrum.
When light passes through a prism, it is refracted, which means it is bent or separated into different colors. This happens because light waves travel at different speeds through different materials, causing them to change direction.
Red light is refracted the least by a prism as it has the longest wavelength.
When white light is passed through a prism, it is refracted at different angles depending on the wavelength (color) of the light. This causes the white light to spread out into its component colors, creating a spectrum of colors from red to violet. This phenomenon is known as dispersion.
Blue light is refracted the most when passing through a prism, followed by green, yellow, orange, and red light in that order. This is due to the different wavelengths of the colors, with blue light having the shortest wavelength and being bent the most as it passes through the prism.
When light passes through a prism, it is refracted slightly and separated into seven individual beams of coloured light - red, orange, yellow, green, blue, indigo and violet.
When light shines through a prism, it is refracted, which means it is bent as it passes through the prism. This bending of light causes it to separate into its component colors, creating a rainbow spectrum.
