For Which Colour Refractive Index Is Minimum?

Which Colour refracts most?

violet lightThe shorter the wavelength of the light, the more it is refracted.

As a result, red light is refracted the least and violet light is refracted the most – causing the coloured light to spread out to form a spectrum..

What is the shortest color wavelength?

violet lightOn one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. It has all the colors of the rainbow.

What is bending of light called?

Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows.

For which Colour of light refractive index of a medium is minimum?

red lightSince velocity v of red light through a medium is maximum, refractive index n for red light will be least.

What is the minimum possible refractive index?

Answer. Refractive index is the ratio of the speed of light in vacuum to the the speed of light in a medium. The speed of light is maximum or highest in vacuum. So the possible minimum value of refractive index is 1.

Which Colour has best refractive index?

Violet lightViolet light has the maximum refractive index and least speed when travelling through a medium since it has the shortest wavelength. Thus, it bends most upon incidence and has maximum deviation.

Which Colour has maximum speed in glass?

redBecause the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.

For which Colour of light critical angle is minimum?

violetAssertion `:` Critical angle of light passing from glass to air is minimum for violet colour. Reason `:` The wavelength of blue light is greater than the light of other colour.

Which is the fastest color?

blueThe Norwegian speedskating team abandoned their traditional red suits for blue ones this Olympics after a report by Norwegian scientists that blue is the fastest color.

For which Colour refractive index of prism is maximum and minimum?

Answer. Refractive index depends up on the wavelength of light with the least wavelength is refracted the most (violet – maximum refractive index), while the light with the maximum wavelength is refracted the least (red – least refractive index).

What is called refractive index?

Refractive Index (Index of Refraction) is a value calculated from the ratio of the speed of light in a vacuum to that in a second medium of greater density.

Which Colour has highest deviation?

Violet lightViolet light has the maximum refractive index and least speed when travelling through a medium since it has the shortest wavelength. Thus, it bends most upon incidence and has maximum deviation.

Which has highest refractive index?

The highest refractive index is of Diamond with its value 2.42.Refractive index of glass is 1.5.Refractive index of water is 1.33.Refractive index of ruby is 1.77.

Which color is the most bent?

violet lightSince violet light has a shorter wavelength, it is slowed more than the longer wavelengths of red light. Consequently, violet light is bent the most while red light is bent the least. This separtion of white light into its individual colors is known as dispersion of light.

What is SI unit of refractive index?

Unit of refractive index (μ) will be the ratio of the unit of speed of light in vacuum(c) to the speed of light in the given medium(v). As you can see, the unit of refractive is 1, which means the refractive index is just a number without any unit.
