What is meant when medium is described as dispersive cite an example of a dispersive medium?
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.
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 do you understand by the angular dispersive power of grating?
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.
When a beam of radiation enters some medium experiences a collision event and fails to exit the medium this is called?
This is called absorption. The beam of radiation is absorbed by the medium, leading to the loss of energy and failure to exit the medium.
The ability of a medium to bounce back after being disturbed is called?
The ability of a medium to bounce back after being disturbed is called resilience.

Is that air a dispersive medium for sound waves?
Yes, air is a dispersive medium for sound waves, but the dispersion is minimal compared to other materials. In air, sound waves of different frequencies travel at slightly different speeds due to variations in temperature, pressure, and humidity. However, this effect is usually negligible over short distances, making air primarily a non-dispersive medium for practical purposes. In contrast, more complex dispersive behaviors are observed in solids and liquids.
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.
What word is used to describe a material that does not dissolve in water?
The glue which does not dissolve in water is called dispersive.
What is the definition of dispersive media?
hahahahhaha
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 is dispersive power and resolving power of a grating?
No
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 dispersive stage of sponges?
medusa, the polyp is the sessile stage
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.
The dissolving medium is also called the?
Substance which is going to dissolve in medium is called solute and the medium is called solvent. solute + solvent = solution
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
