Why is the constant deviation spectrometer named so?
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
Why is white light dispersed by a glass prism?
When white light(composite light) consisting of various colors is passed through a prism, light of different colors will be deviated through different angles. Since the deviation is related to refractive index and refractive index to the color of light the deviation produced for different colors are different for same prism.That is the refractive indices are different for the various colors and this difference in the refractive indices is responsible for dispersion.
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.
How can you cause light separated by a prism to combine?
take away the prism
What shape has 6 vertices and 9 edges?
a triangular prism has 6 vertices.
What is the formula for calculating the angle of deviation in a prism?
The formula for calculating the angle of deviation in a prism is: Angle of Deviation (Refractive index of the prism - 1) x Prism angle.
What is the difference between ordinary prism and constant deviation prism?

What is the advantage of keeping the prism in minimum deviation?
By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.

How is angle of prism and angle of deviation related?
angle of deviation = angle of prism x ( refractice index -1)
What is the minimum deviation of prism whose refractive index is three to the power half?
The minimum deviation of a prism can be calculated using the formula: δ = (n - 1)A, where δ is the minimum deviation, n is the refractive index of the prism, and A is the angle of the prism. If the refractive index of the prism is three to the power of half, or √3, and the value of A is known, the minimum deviation can be calculated using the formula.
Why does the angle of deviation of a prism decreases first and then increases?
As the angle of incidence is increased, angle of deviation 'd' decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased. Let dm be the angle of minimum deviation. The refracted ray in the prism in that case will be parallel to the base.
Does the angle of minimum deviation depend upon the colour of light used?
Yes, the angle of minimum deviation does depend on the color of light used. This is because different colors of light have different wavelengths, which can lead to variations in how light is refracted when passing through a prism, causing the angle of minimum deviation to differ for each color.
Do light passing through a prism have a maximum deviation?
Yes, light passing through a prism has a maximum deviation angle which occurs at a specific angle called the angle of minimum deviation. This angle depends on the material and shape of the prism.
When will the minimum deviation occur in the experiment of the spectrometer-refractive index?
The minimum deviation in a spectrometer experiment occurs when the refracted ray is parallel to the base of the prism, resulting in the prism being in a state of minimum deviation.
