Describe the term Specular Reflection
Describe briefly the term Specular Reflection?
Expert
The Specular reflection is when the reflection is much stronger in one viewing direction that is, there is a bright spot termed as specular highlight. It is readily apparent on the shiny surfaces. For an ideal reflector, like a mirror, the angle of incidence equal to the angle of specular reflection.
Light is reflected mostly in the direction of the reflected ray and it is attenuated by an amount dependent on the physical properties of the surface. As the light reflected from the surface is mostly in the direction of the reflected ray the place of the observer finds out the perceived illumination of the surface.
What do you mean by the term alloy? Briefly illustrate it.
Compton Effect (A.H. Compton; 1923): The effect which describes those photons (that is the quantum of electromagnetic radiation) has momentum. The photon fired at a stationary particle, like an electron, will communicate momentum to t
Spin-orbit effect: The effect that causes atomic energy levels to be split since electrons contain intrinsic angular momentum (that is spin) in summation to their extrinsic orbital angular momentum.
Weiss constant: The characteristic constant dependent on the substance, employed in computing the susceptibility of the paramagnetic materials.
Dielectric is a material in which energy can be accumulated. Ideally, it is a non-conductor of electric charge like insulators, but an efficient supporter of electrostatic fields. The
What do you mean by the term Newton meter? Explain briefly?
Avogadro's hypothesis (Count A. Avogadro; 1811): Equivalent volumes of all gases at similar temperature and pressure contain equivalent numbers of molecules. This is, in fact, true only for the ideal gases. <
A thermocouple of K type is suddenly exposed to air with temperature of 1273K, Initial temperature was 293 K. Calculate the time needed for the thermocouple read the temperature with accuracy of better that 99%. Ignore radiation and conduction. The measuring element has a ball shape of diameter o
