A prism breaks white light into what?
A dispersive prism can break light into its spectral colours, or the colours of the rainbow
What is dispersive power of a grating?
Dispersive power is defined as the rate of change of angle of diffraction with the change of wavelength in a particular order of spectrum. Type your answer here...
What is the difference between dispersive and resolving power of diffraction grating?
The ability of an optical instrument expressed in numerical measure to resolve the image of two nearby points is termed as resolving power. The dispersive power of a diffraction grating is defined as the rate of change of the angle of diffraction with the wavelength of lite. S M SOHEL RANA IU
Why a medium is called as dispersive medium?
group velocity depends upon the frequency of the wave. such type of materials called dispersive medium.
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.
What is meant by dispersive power of prism?
the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
Can you use a sodium lamp for finding dispersive power of prism?
yes of-course

How is a rainbow similar to a prism?
Rainbow is not similar to prism.A rainbow is an optical and meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky.A prism is a transparent optical element with flat, polished surfaces that refract light with at least two of the flat surfaces having an angle between them.A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow).So the water droplets can be considered as being similar to a dispersive prism.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
What is an Abbe number?
An Abbe number is a number which represents the reciprocal of the dispersive power of a substance with transparent qualities.
What is achromatic lens and what is its relation to power and dispersive power?
An achromatic lens is one without chromatic distortion (gives no colour fringing). The achromatism has no direct relation to power.
