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?
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.
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 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.
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.
Do sponges have bone?
no sponges do not have bones
