It works under the principle of refraction and the phenomenon of dispersion.
What else can I help you with?
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.
What is dispersive power of a prism?
.04 to .05 typically about 0.47
What is dispersive power and resolving power of a grating?
No
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.
How is a rainbow similar to a prism?
Rainbow is not similar to prism.A rainbow is an optical and meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky.A prism is a transparent optical element with flat, polished surfaces that refract light with at least two of the flat surfaces having an angle between them.A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow).So the water droplets can be considered as being similar to a dispersive prism.
What do you call a prism spreading out light into colors?
It is called Visible light Spectrum.
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.
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
A prism breaks white light into what?
A prism breaks white light into the colors of the visible spectrum, which are red, orange, yellow, green, blue, indigo, and violet. This process is known as dispersion, where each color is separated based on its wavelength, with red having the longest wavelength and violet having the shortest.
