Diffuse reflection is a feature of light reflected from a dull, and a non shiny surface. In this objects illuminated solely by diffusely reflected light exhibit an equivalent light intensity from all sighting directions. That is, in diffuse reflection light incident on the surface is reflected uniformly in all directions and is attenuated through an amount dependent on the physical properties of the surface. As light is reflected uniformly in all directions the perceived illumination of the surface is not dependent on the place of observer. The Diffuse reflection models the light reflecting properties of the matt surfaces that is, surfaces which are grainy or rough which tend to disperse the reflected light in all the directions. This dispersed light is termed as diffuse reflection.
Negative feedback principle: It is the idea that in a system where there are self-propagating situations, those new situations tend to act against formerly existing situations. Such a principle is in actuality a restatement of the conservation law.
Explain Conservation laws and illustrations of conservation laws (Conservation of mass-energy, electric charge, linear momentum and angular momentum) ? Conservation laws: The law which states that,
Brownian motion - The continuous random motion of a solid microscopic particle whenever suspended in a fluid medium due to the effect of ongoing bombardment by molecules and atoms.
Bell's inequality (J.S. Bell; 1964) - The quantum mechanical theorem that explains that if the quantum mechanics were to rely on the hidden variables, it should have non-local properties.
Hubble constant: H0 (E.P. Hubble; 1925): The constant that determines the relationship among the distance to a galaxy and its velocity of recession due to the growth of the Universe. As the Universe is self-gravitating, it is not trut
My question is Eph = hcT. I have to rearrange the equation to make b b the subject and also find the SI units for b and how and why they are those units.....
Define Hertz or SI unit of frequency: Hertz: Hz (after H. Hertz, 1857-1894): The derived SI unit of frequency, stated as a frequency of 1 cycle per s; it therefore has units of s-1.
what is the characteristics of electronics ?
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
When one coil of a magnetically coupled pair has a current of 5.0A, the resulting fluxes Φ11 and Φ21 are 0.2mWb and 0.4mWb, respectively. If the turns are N1 = 500 and N2 = 1500, find L1, L2, M and the coeffici
