What is the optical Density of water

Posted by Prateeksha Dhianeshwar 5 years, 11 months ago

CBSE > Class 07 > Science

1 answers

.. ... 5 years, 11 months ago

Optical density is the extent to which the medium allows refraction through it. It does not have any value assigned to it, and so has no value for water or air or any other material. Optical density is related to the refractive index. Actually it is the other way round. The refractive index of a material depends on its optical density. Greater refractive index suggests that the medium has high optical density, means the medium refracts the light to a greater extent. Optical density is however not related to the physical density of a medium. The physical density is ratio of mass to volume.

Obaidullah Khan 5 years, 11 months ago

Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic, and fluorite. A dispersive prism can be used to break light up into its constituent spectral colors (the colors of the rainbow). The wireless spectrum consists of electromagnetic radiation and frequency bands. ... The wireless spectrum frequencies used in communication are regulated by national organizations, which specify which frequency ranges can be used by whom and for which purpose.

.. ... 5 years, 11 months ago

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. A spectrum (plural spectra or spectrums) is a condition that is not limited to a specific set of values but can vary, without steps, across a continuum. The word was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism.

If we are in a room of mirrors anx beam of light comes will it reflect???

Posted by V J 5 years, 11 months ago

1 answers

Meghna Thapar 5 years, 10 months ago

When two plane mirrors are kept inclined at an angle, they can form multiple images of an object because the image of the object formed in one plane mirror acts as object for the other plane mirror.

The two plane mirrors arranged at right angles to each other form three images of an object placed between them. As the angle between the two plane mirrors decreases, the number of images formed increases. If an object is placed between two parallel plane mirrors facing each other, then an infinite number of images should be formed.
