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

How do you model angular separation?
by doing x to the power of the sqrt of the log of 72
What is achromatic lens and what is its relation to power and dispersive power?
An achromatic lens is a type of lens designed to minimize chromatic aberration, which causes colors to focus at different points. It is made by combining two different types of glass with varying refractive indexes to reduce this effect. The power of an achromatic lens is related to its ability to focus light without chromatic aberration, while its dispersive power is diminished due to the combination of different glass types.
