What happens when white light is incident on an inverted prism?
When white light is incident on an inverted prism, the different colors in the light spectrum get separated due to dispersion. This is because each color in the white light spectrum bends at a different angle as it passes through the prism, creating a rainbow effect. The colors are then displayed in a spectrum ranging from red to violet.
What happens when the incident ray is at an angle of 90 and deg to the prism?
When the incident ray is at an angle of 90 degrees to the prism, it will not enter the prism but will reflect off of it. This occurs because the light undergoes total internal reflection at the interface between the two mediums due to the critical angle being reached.
If the laser that emits red light shines on a prism what will emerge?
When red light from a laser shines on a prism, it will be refracted (bent) by the prism and split into its component colors (red, orange, yellow, green, blue, indigo, and violet). This is due to each color having a different wavelength and therefore a different angle of refraction when passing through the prism.
How you will use two identical prisms so that a narrow beam of white light incident on one prism emerges out of second prism as white light . draw the diagram?
To ensure that a narrow beam of white light emerging from one identical prism exits from the second prism as white light, position the prisms such that the beam enters the first prism at an angle. The first prism will refract the light, separating it into its component colors. Then, align the second prism such that the emerging beam enters it at the appropriate angle to recombine the colors back into white light. Unfortunately, I can't draw diagrams, but you can visualize two prisms arranged in a straight line, with the first prism receiving the light beam and the second prism oriented to receive the refracted light from the first.
What is the definition of angle of minimum deviation for prism?
The angle of minimum deviation for a prism is the angle at which the deviation of light passing through the prism is minimized, resulting in the least amount of dispersion. It is the angle at which the emerging light beam is least deviated from its original path after passing through the prism.
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.

What happens when light travels into a prism?
As light incidents normally then nothing happens. But if light is incident at an acute angle with one refracting face then composite white light gets dispersed while coming out of the other refracting face. Usually as light is incident at an acute angle even in a glass slab then dispersion tales place as refractive index of the glass is different for different colours and so having different angle of refraction. But as it has to emerge out of the slab at the opposite face there once again all colours get mingled and only white light comes out. But in case of prism that chance is missing and so dispersion leads to have VIBGYOR
What is the function of prism?
It transforms incident rays (say, from the Sun) of white light [that contains almost every light frequency] into, by Refraction, a Rainbow. Please ask next - What are the main Astronomical uses of the Prism.

What are two conditions for minimum deviation in a prism?
The two conditions for minimum deviation in a prism are that the incident angle and the angle of refraction at the prism's surfaces must be equal, and the light ray must pass symmetrically through the prism. This occurs when the angle of incidence equals the angle of emergence, resulting in the light ray entering and exiting the prism at equal angles relative to the prism's base. Additionally, the angle of deviation is minimized when the light ray travels in a straight path through the prism's apex.
How does the angle of minimum deviation of glass prism varyif the incident voilet light is replaced with red light?
The angle of minimum deviation of a glass prism is smaller for red light compared to violet light. This is because red light has a longer wavelength, which causes it to refract less through the prism. As a result, the prism bends the red light less, leading to a smaller angle of minimum deviation.
What is the definition of angle of minimum deviation for prism?
The angle of minimum deviation for a prism is the angle at which the deviation of light passing through the prism is minimized, resulting in the least amount of dispersion. It is the angle at which the emerging light beam is least deviated from its original path after passing through the prism.
How many colors in a prism?
A prism is normally colourless. White light, incident upon the prism, is broken down into a continuum of wavelengths. Although there are thus an infinity of colours, customarily, they are classed into the following seven: Red, Orange, Yellow, Green, Blue, Indigo and Violet.
What is incident ray of light?
An incident ray of light is a ray of light that strikes a surface or boundary between two different materials. It represents the direction in which the light is traveling before it encounters the surface.
