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.
Hawking radiation (S.W. Hawking; 1973): The theory which black holes emit radiation similar to any other hot body. The virtual particle-antiparticle pairs are continuously being made in supposedly empty space. Infrequently, a pair wil
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
1. Solve Laplace's equation for the electrical potential between two infinite parallel plates, which have a charge density per unit area -on one plate and a charge density per unit area -! on the second plate, and determine the electric field between the plates from t
Rayleigh-Jeans law: For a blackbody at the thermodynamic temperature T, the radiance R over a range of frequencies between the nu and nu + dnu is specified by: R = 2 pi nu2 k T/c2.<
Uncertainty principle (W. Heisenberg; 1927): A principle, central to the quantum mechanics that states which two complementary parameters (like energy and time, position and momentum, or angular momentum and angular displacement) can’t both be r
Ergosphere: The area around a rotating black hole, among the event horizon and the static limit, where the rotational energy can be removed from the black hole.
Explain Ampere's law? Ampere's law (A.M. Ampere):
Explain in brief that the gas encompass density or not?
Mach's principle (E. Mach; c. 1870): The inertia of any specific particle or particles of matter is attributable to the interaction among that piece of matter and the rest of the world. Therefore, a body in isolation would contain no inertia.
Tesla: T (after N. Tesla, 1870-1943): The derived SI unit of the magnetic flux density stated as the magnetic flux density of a magnetic flux of 1 Wb via an area of 1 m2; it therefore has units of Wb/m2.
