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.
Mach number (E. Mach): It is the ratio of the speed of an object in a specified medium to the speed of sound in that medium.
Second: s: The basic SI unit of time, stated as the period of time equivalent to the duration of 9 192 631 770 periods of the radiation analogous to the transition between the two hyperfine levels of the ground state of cesium-133 atom.
Josephson effects (B.D. Josephson; 1962): Electrical effects examined whenever two superconducting materials are separated by a thin layer of the insulating substance.
Briefly explain the measure of the force of gravity on the object?
When air is compressed adiabatically the law connecting the absolute temperature T and the pressure P is of the form T = A.Pn where A and N are constants. Show by drawing a suitable linear graph that the experimental dat
Boltzmann constant: k (L. Boltzmann) - The constant that explains the relationship between kinetic energy and temperature for molecules in an ideal gas. This is equivalent to the 1.380 622 x 10-23 J/K.
The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
Planck constant: h: The basic constant equivalent to the ratio of the energy of a quantum of energy to its frequency. This is the quantum of action. This has the value 6.626 196 x 10-34 J s.
Briefly illustrate all the Newton s laws of motion?
Doppler Effect (C.J. Doppler): The waves emitted by a moving object as received by an observer will be blue shifted (compressed) when approaching, redshifted (that is, elongated) if receding. This takes place both in sound and also el
