What storage medium are phase change alloys used?
Fatty
When light enters from denser medium to rare medium what happens to its phase change?
phase angle of 0 degree
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
NO
What determines the direction of energy transfer in a phase change?
light is form of energy then light is reflected at boundary of rarer medium and denser medium reflected ray is phase change of 180 degree's energy is phase changed direction of energy is opposite of transfer ed way
What are the phases phase contrast microscope?
phase change refers to the changes in the amplitude, and wavelength of the light when it passes from one medium to the other...
Why phase change of 180 takes place when wave enter from rarer medium to denser medium?
The displacement is a peculiar state, due to the fact that this is one of the special situations in which energy is completely destroyed and conservation of energy does not take place; hence the phase change
How is a wave changed by reflection?
When a wave traversing in a medium of less refractive index gets reflected at a medium of greater refractive index then wave undergoes a phase change of pi radians. But if the same reflection takes place as the wave traverses from a medium of greater refractive index to that of less refractive index, then no such phase change. The later reflection is known as total internal reflection. So as light traversing in air gets reflected at glass then phase change of pi radians occurs.
What is a CD-RW?
This is a rewritable CD introduced in 1997. A CD-RW disc can be written and erased roughly 1000 times. While a prerecorded compact disc has its information permanently stamped into its polycarbonate plastic substrate, a CD-RW disc contains a phase-change alloy recording layer composed of a phase change material. CD-RWs are not as reliable for long-term storage; however, under recommended storage conditions, CD-RW should have a life expectancy of 25 years or more (as compared to 100+ years for CD-R)
Is Alloy a solution or suspension?
Alloy is a mixture of elements (one metal plus other metals or non metals). An alloy can be considered as a solid solution, in a single phase or more. Atoms in an alloy have matallic bonds.
Is it possible to differentiate between hypo- and hypereutectic compositions of an alloy based on a single cooling curve and the phase diagram of the alloy?
Try it.
What is meant by medium?
the component in which the dispersed phase is suspended is called dispersing medium
Is jelly an example of emulsions?
No, for jellies, dispersion phase is liquid and dispersion medium is solid. And for emulsions,both dispersion phase and dispersion medium is liquid.
