It works under the principle of refraction and the phenomenon of dispersion.
the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
No, sodium lamps emit monochromatic light, which is not suitable for finding the dispersive power of a prism. To determine the dispersive power of a prism, you need light that contains multiple wavelengths. White light, such as from a sunlight or incandescent lamp, is typically used for this purpose.
.04 to .05 typically about 0.47
No
When a medium is described as dispersive, it means that the speed of light through that medium depends on the frequency or wavelength of the light. An example of a dispersive medium is a prism, where white light is separated into its component colors due to their different speeds in the medium.
The dispersive power of a grating refers to its ability to separate different wavelengths of light. It is determined by the formula D = δλ/δθ, where δλ is the change in wavelength and δθ is the change in angle. Gratings with higher dispersive power can separate wavelengths more effectively.
The angular dispersive power of a grating is a measure of its ability to spread out different wavelengths of light as they pass through the grating at different angles. It quantifies how effectively the grating separates colors or wavelengths of light based on their angles of diffraction. A grating with higher angular dispersive power will produce a more pronounced separation of wavelengths or colors.
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.
It is called Visible light Spectrum.
An Abbe number is a number which represents the reciprocal of the dispersive power of a substance with transparent qualities.
The dispersive power of a diffraction grating refers to its ability to separate light into its component wavelengths, typically measured as the rate of change of diffraction angle with respect to wavelength. On the other hand, the resolving power of a diffraction grating refers to its ability to distinguish between closely spaced spectral lines, which is determined by the number of resolvable spectral lines that can be observed. In essence, dispersive power deals with the spreading of light into different wavelengths, while resolving power deals with the ability to distinguish between closely spaced wavelengths.
A prism breaks white light into the colors of the visible spectrum, which are red, orange, yellow, green, blue, indigo, and violet. This process is known as dispersion, where each color is separated based on its wavelength, with red having the longest wavelength and violet having the shortest.
