What storage medium are phase change alloys used?
Fatty
Is there any phase change occurred when sound wave refracted from denser medium to a rarer medium?
No, there is no phase change that occurs when a sound wave refracts from a denser medium to a rarer medium. The wavelength and frequency of the wave may change due to the change in speed, but the phase remains the same.
When light enters from denser medium to rare medium what happens to its phase change?
When light enters from a denser medium to a rarer medium, the phase change it experiences is a shift towards a longer wavelength, known as refraction. This shift in phase is due to the change in the speed of light as it travels through the different mediums.
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
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...
Phase diagram of aluminium copper alloy?
The phase diagram of an aluminum-copper alloy typically shows two phases: a solid solution phase (α-phase) and a eutectic phase (θ-phase). As the temperature decreases, the α-phase solidifies first, followed by the eutectic reaction where both phases form simultaneously. The diagram helps in understanding the temperature and composition ranges where different phases exist in the alloy.
How does the phase shift affect refraction in the context of wave propagation?
The phase shift affects refraction in wave propagation by changing the direction of the wave as it passes from one medium to another. This change in direction is caused by the difference in the speed of the wave in each medium, which leads to a change in the wavelength and frequency of the wave.
What is the Phase diagram of nickel copper alloy having 50 copper and 50 nickel at temperature from 1400C to 1200C?
At 1400C Ni-50Cu alloy is in the liquid state and at 1200C it is in a single-phase solid state, having the face-centered cubic (FCC) crystallographic structure. Alojz Kajinic, Ph.D. http://www.calphad.com/
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.
Can you calculate the melting point of an alloy?
To calculate the melting point of an alloy, one must consider the melting points of the individual elements in the alloy and their relative proportions. The melting point of an alloy is usually lower than that of its individual components due to the formation of a new phase. Phase diagrams are often used to predict the melting behavior of alloys.
