In white light various colors of light are mixed together, primarily blue yellow and red. When white light in air passes through a glass prism having a certain refractive index, all the differently colored lights have the same angle of incidence (θ) but each differently colored light has a different emergent angle of refraction, going from red light (at the minimum angle) to blue light (having the maximum angle).
According to the refractive index formula n = sin θ ／ sin γ, where n is the refractive index of the prism, sin θ is the sine of the angle of incidence (θ) and sin γ is the sine of the angle of refraction (γ).
I believe that is just a different way of describing the effect, not an explanation. Red light in glass travels at a lower speed than in air or vacuum. So when a wavefront hits a flat surface of glass at an angle, the end of the wave front inside the glass travels more slowly than the part of the wavefront that has not yet entered the glass. But the wave front must still be continuous all along its length, and the only way to achieve that is if the wavefront inside the glass proceeds in a tilted direction. The slower the light in the glass, the bigger the change in angle. Green light in glass travels faster than red and slower than blue. So the different colors are spread into different angles of refraction.

When blue light goes through a prism what happens?
Blue light enters the prism and is refracted (bent) by the glass and emerges as blue light on the other side. Blue light is bent (refracted) most due to its slow(er) speed than say Red light which is faster and has a longer wavelength. Newton did an experiment like this and concluded that white light was made up of different colours of light together. Shine a white light through a prism and it will emerge as all the colours of the rainbow. Blue light is unchanged as it consists only of blue light Answered by Chris Banks.
How does a prism allow us to see more than just white light?
I got this ! A prism allows you to see more then just white light because the sun reflects to the prism and then that light gets absorbed and reflected back into our eyes to see all the colors of the spectrum.
What affect does a different colored light bulb have on a prism?
A prism will split light into its component colors. If a colored light is used, there will be less colors in the split light. A beam from a red light for instance will have very little blue or green light in it so you will not get the full spectrum from the prism.
What does a prism do with white light?
A prism can help us understand the refraction and the reflection of light when it asses between 2 different mediums ( from one medium into another less refractive or from one medium into another more refractive ) and the ray of light may emerge out of the prism by refraction or by reflection and sometimes by total internal reflection ( by obeying the 2 laws of reflection and by making the angel of incidence equal to the angle of reflection ) and sometimes it may continue its path without deviation that is when the angle of incidence is equal to 0 degrees then the angle of refraction will be equal to 0 degrees this is called undeviated !It separates the wavelengths contained in a beam of light.
When white light passes through a prism which will be bent more the red or green light?
In case of visible region, VIBGYOR, violet has the maximum bending.
In glass blue light bends more than green light and green light bends more than red light Which one of the following has the highest index of refraction in glass?
The blue light is refracted more.
What color of the rainbow bends the most?
red. bending is a physical phenomenon called defraction , the less frequency ( or the longer the wave length) the more the defraction. since the red has the least frequency it bends more than any colour.
Which colour refracts more in a prism yellow or blue?
Blue refracts the most in a prsm than yellow
Which wavelength of visible light bends the most when refracted by a prism?
When light passes through a prism, the angle of deviation of any light beam is inversely proportional to its wavelengh. Since, violet color has least wave length, it bends the most and the red bends the least.Dhirender Sharma
In the different colors of light which is the bent most and the least?
The amount of bending that occurs when light passes through a prism depends on the wavelength of the light. Blue light is bent the most, while red light is bent the least. This is due to the shorter wavelength of blue light compared to red light.
Which color of light moves the fastest through a prism?
All colors of light travel at the same speed in a vacuum, which is the speed of light (299,792 kilometers per second). However, different colors of light bend at slightly different angles when passing through a prism due to their differing wavelengths. Blue light bends slightly more than red light, so it may be perceived as moving faster through a prism.
When white light lite is dispersed by a prism a spectrum is obtained on a screen if you pass a beam of pure blue light through a prism what would you see on the screen?
We see different colours of light because of their different frequencies. White light is actually lots of different frequencies, you see a spectrum because when light diffracts (slows down and changes direction) each frequency diffracts by a different amount, some bend more than others. Because blue light is only one frequency it will not produce a spectrum, so all the light bends by the same ammount.
Why does a prism cause white light to separate into colors of a spectrum?
Light bends in glass dependent on its thickness. Violet comes from the thin part and red from the thick part of a prism.
Which colour bends the most when white light is passed through a prism?
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.
When white light is passed through prism why is it observed that violet light bends more than red light?
This phenomenon is due to the property of refraction, where different colors of light have different wavelengths and therefore refract at different angles when passing through a medium like a prism. Violet light has a shorter wavelength compared to red light, causing it to bend more when passing through the prism. This separation of colors is known as dispersion.
Which colour of light deviates more and why?
Blue light deviates more than red light when passing through a prism because it has a shorter wavelength and higher frequency, causing it to refract more. This leads to different angles of separation for the colors of the light spectrum as they pass through the prism.
Dispersion of light why does blue slow down the most yet bends the most?
Blue light slows down the most and bends the most because it has a shorter wavelength compared to other colors in the visible spectrum. In a medium like glass or water, the speed of light is inversely proportional to the wavelength, so shorter wavelengths slow down more. When light enters a medium at an angle, it bends due to refraction, and this bending effect (refractive index) is greater for shorter wavelengths like blue light.
