Are porifera ever planktonic?

Many sponges are planktonic in their larval stage. Full grown sponges are sessile.


What group of animals does not go through the gastrula stage?

It's commonly believed that sponges are a group of animals that don't go through the gastrula stage. However, some scientists disagree and believe that sponges do go through gastrulation.


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 the definition of dispersive media?

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 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.


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.


Why a medium is called as dispersive medium?

A medium is called dispersive when it causes different frequencies of light to travel at different speeds, leading to the separation of colors. This occurs because the refractive index of the medium varies with the frequency of light, resulting in dispersion.


Are sea sponges decomposers?

No, sea sponges are not decomposers. Sponges are filter feeders.
