Does solar radiation encompass a complete spectrum
Does solar radiation encompass a complete spectrum of all the forms of electromagnetic radiation?
Expert
Yes it definitely does. It comprises all the forms of radiation; however 99% of its energy is taken by radiation with wavelengths among 278 and 4600 nm, with the utmost at 472 nm.
what should be the choice of standard unit.
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: Q : What is Super fluidity Super fluidity : Super fluidity: The phenomenon by which, at adequately low temperatures, a fluid can flow with zero (0) viscosity. These causes are related with the superconductivity.

Briefly illustrate how do fireworks turn to shapes similar to hearts and stars?
Balmer series (J. Balmer; 1885): An equation that explains the emission spectrum of hydrogen whenever an electron is jumping to the next orbital; four of the lines are in visible spectrum, and the remainder (residue) are in the ultraviolet.
Planck equation: The quantum mechanical equation associating to the energy of a photon E to its frequency nu: E = h nu.
Write down a brief note on the classification of Alloys?
Pascal's principle: The pressure exerted to an enclosed incompressible static fluid is transmitted undiminished to all portions of the fluid.
Rayleigh criterion: resolving power: The criterion for determining how delicately a set of optics might be able to differentiate. This starts with the supposition that central ring of one image must fall on the first dark ring of the other; for
