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.
What is the reason that heat causes matter to expand? Briefly explain it.
Loschmidt constant: Loschmidt number: NL: The total number of particles per unit volume of an ideal gas at standard pressure and temperature. It has the value of 2.687 19 x 1025 m-3.
Describe the reason in short why the length of a standard meter re-defined in the year of 1983?
Gaia hypothesis (J. Lovelock, 1969): The thought that the Earth as an entire must be regarded as a living organism and that biological procedures stabilize the atmosphere.
Faraday's law (M. Faraday): The line integral of the electric field about a closed curve is proportional to the instant time rate of change of the magnetic flux via a surface bounded by that closed curve; in the differential form,
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
Universal constant of gravitation: G The constant of proportionality in the Newton’s law of universal gravitation and that plays a comparable role in Sir Einstein's general relativity. This is equivalent to the 6.672 x 10-1
Planck radiation law: The law which explained blackbody radiation better than its precursor, therefore resolving the ultraviolet catastrophe. This is based on the supposition that electromagnetic radiation is quantized. Q : Define Second or SI unit of time 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.
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.
Malus' law (E.L. Malus): The light intensity I of a ray with primary intensity I0 travelling via a polarizer at an angle theta among the polarization of the light ray and the polarization axis of the polarizer is specified by: Discover Q & A Leading Solution Library Avail More Than 1412615 Solved problems, classrooms assignments, textbook's solutions, for quick Downloads No hassle, Instant Access Start Discovering 18,76,764 1923316 Asked 3,689 Active Tutors 1412615 Questions Answered Start Excelling in your courses, Ask an Expert and get answers for your homework and assignments!!
