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.
Landauer's principle: The principle which defines that it doesn't explicitly take energy to calculate data, however instead it takes energy to remove any data, as erasure is a vital step in computation.
Paschen series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the third orbital. Each and every line is in the infrared part of the spectrum.
Does water drain contradict clockwise in the northern hemisphere and clockwise in the southern hemi-sphere? Briefly explain it.
Wiedemann-Franz law: It is the ratio of the thermal conductivity of any pure metal (substance) to its electrical conductivity is just about constant for any specified temperature. This law holds pretty well apart from at low temperatures.
Tachyon paradox: The argument explaining that tachyons (should they subsist, of course) can’t carry an electric charge. For an imaginary-massed particle travelling faster than c, less energy the tachyon has, the faster it travels, till at zero e
Lux: lx: The derived SI unit of the illuminance equivalent to the illuminance generated by a luminous flux of 1 lm distributed consistently over a region of 1 m2; it therefore has units of lm/m2.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Van der Waals force (J.D. van der Waals): The forces responsible for non-ideal behavior of gases, and for lattice energy of molecular crystals. There are three main causes: dipole-dipole interaction; dipole-induced dipole moments; and dispersion a for
What do you mean by the term positron? Explain in short.
