To find the refractive index of a glass block for a particular wavelength of light, shine a beam of light of that wavelength through a material for which the refractive index n1 is known onto the glass block such that the angle between the beam and the block's surface θ1 is between zero and 90 degrees. Measure the angle between the part of the beam that enters the block and the block's surface θ2 and use Snell's law:n2 = n1 cos(θ1) / cos(θ2).Note: Typically Snell's law is expressed in terms of the angle between the beam and the direction normal to the interface and there for sines are used instead of cosines, but the use of cosines allowed the question to be answered without assuming knowledge of the concept "normal" to the interface.
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
Another name for light beam is ray of light. Other similar names are beam of light, shaft of light, and irradiation.
How absorption and scattering can affect a beam of light is if the beam of light is farther away from an object, the light would be dimmer. But, if the beam of light was closer to the object, then the light would appear brighter.

that depends on the refractive index of the surface refracting the light beam. This is also affected by the light's wavelength and temperature of the media. Sage.
It depends on the refractive index of the plastic. There are many different kinds of plastic and they do not have the same refractive index.
Red bends the least. If you look at a prism with a beam of light shining through it, you will see violet is bent the most. This due to the refractive index of the glass changing the wavelength. Velocity & frequency are components of wavelength. So the refractive index is a ratio by which the speed of light is changed. I am not sure if frequency is changed.

Not much because the light has to travel a distance in the medium with a different refractive index in order for the dispersion to become obvious. If you look very closely you will see some dispersion but it may be microscopic.
Yes, anyone can use a prism to separate light into the colors of the spectrum. It is, in fact, fairly simple to do. You simply place the prism into a beam of light and orient it so that the light beam enters on face at an angle, travels through the prism approximately parallel to a second face, and exits the third face at an angle similar to its angle of entry. The light beam will now be deflected by a total angle which depends on the refractive index of the material from which the prism is made.
