An Abbe number is a number which represents the reciprocal of the dispersive power of a substance with transparent qualities.

the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
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.
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.
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.
It works under the principle of refraction and the phenomenon of dispersion.
An Abbe number is a number which represents the reciprocal of the dispersive power of a substance with transparent qualities.
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

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.
hahahahhaha
Power 2: units digit 9. Multiply by 49 again to get power 4: units digit 1. So every 4th power gives units digit 1. So 16th power has units digit 1, so the previous power, the 15th must have units digit 3.
