II) It cannot be dispersed
III) It can be reflected *
Answer:
It can be refracted
Explanation:
When a single wavelength wave which is known as a monochromatic light is passed from one transparent medium to the other, it can refract. This refraction can only be seen if the light enter the medium at some angle.
It is the minimum amount of material needed to start a fusion reaction.
It is the minimum amount of material needed to sustain a fission reaction.
It is the minimum amount of material needed to sustain a fusion reaction.
Answer;
C.It is the minimum amount of material needed to sustain a fission reaction.
Explanation;
-A critical mass is the smallest or the minimum amount of fissile material needed for a sustained nuclear chain reaction. A critical mass must be achieved in order for the chain reaction to continue and release the atomic energy. A critical mass is needed for both a nuclear reactor and an atomic or hydrogen bomb.
-The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross section), its density, its shape, its enrichment, its purity, its temperature, and its surroundings.
The correct answer for above statement is:
c.It is the minimum amount of material needed to sustain a fission reaction.
Explanation:
A nuclear reaction is taken into account to be the method during which 2 nuclear paticles (two nuclei or a nucleus and a nucleon) move to supply 2 or a lot of nuclear particles or gamma rays.
Thus, a natural action should cause a change of a minimum of one nuclide to a different. typically if a nucleus interacts with another nucleus or particle while not dynamic the mature of any nuclide, the method is mentioned a nuclear scattering.
The important mass is that the smallest amount of fissile material required to sustain nuclear reactions below expressed conditions

This other guy said it was plasma
The behavior of light makes it possible for you to see a spectrum of colors in a spray of water on a sunny day is refraction. The refractive index of a medium is dependent on the wavelength and hence light of different wavelength undergo refraction by different angle which causes the splitting of light beam in different color.
The answer is refraction?
