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.

What is dispersive power of a grating?
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.
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
What is dispersive power of a prism?
.04 to .05 typically about 0.47
A motorcycle generates 500W of power The torque is 50.0 N m What is the angular velocity?
General formula used to calculate torque from power is torque=power*9.55/rpm so,using your data,50=500*9.55/N(rpm) i.e.,N(rpm)=95.5rpm. Angular Velocity=3.147*d*N/60 Unless the diameter is unknown its not possible to calculate the angular velocity.Once diameter is known it can substituted in the above mentioned formula.
Why each of the coupling must be set in certain way to achieve uniform angular transmission?
To achieve uniform angular transmission in couplings, each coupling must be set in a certain way to ensure proper alignment of the shafts. Misalignment can cause angular misalignment of the shafts which leads to vibration, wear, and potential failure of the coupling. Proper alignment ensures that the shafts are in line, allowing for smooth and uniform transmission of power between them.

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 ..
What are Resolving power and dispersive power of a prism?
Resolving power of a prism refers to its ability to distinguish between two closely spaced wavelengths of light, determined by the angular dispersion of the prism; a higher resolving power means better separation of wavelengths. Dispersive power, on the other hand, quantifies how effectively a prism separates light into its constituent colors, defined as the ratio of the difference in the refractive indices of the material for two wavelengths to the difference in their wavelengths. Both properties are essential in optical instruments for achieving high-quality spectral analysis.
What are the units of dispersive power?
Dispersive power is a dimensionless quantity, indicating the ability of a medium to separate different wavelengths of light. It is often expressed as the ratio of the difference in refractive indices of two wavelengths to the refractive index of a third wavelength. Since it is a ratio of refractive indices, which are also dimensionless, dispersive power has no units.
Can you use a sodium lamp for finding dispersive power of prism?
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.
Why must the slit width of a prism monochromator be varied to provide constant effective bandwidths but a nearly constant slit width provides cnstant bandwidth with a grating monochromator?
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
What is the principle of dispersive power of prism?
It works under the principle of refraction and the phenomenon of dispersion.
What is dispersive power or resolving power?
Dispersive power refers to the ability of an optical element, such as a prism, to separate light into its constituent colors based on their wavelengths. It is quantified by the ratio of the difference in the angles of deviation for two wavelengths to the difference in their wavelengths. Resolving power, on the other hand, is the ability of an optical instrument, like a microscope or telescope, to distinguish between closely spaced objects or wavelengths. In essence, while dispersive power focuses on the separation of colors, resolving power emphasizes the detail and clarity in distinguishing features.
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.
