Describe briefly the term Specular Reflection?
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 nu^{2} k T/c^{2}.<
Explain Poisson equation and Poisson spot:
Poisson equation (S.D. Poisson): The differential form of Gauss' law, that is,
div E = rho,
Pois
Obtain the “dot” equivalent for the circuit shown below and use it to find the equivalent inductive reactance.
Calculate the hot and cold temperature after 25 orbits. Assume a 100kg spherical spacecraft made of aluminum. Assume that the spacecraft is in an equatorial orbit. How is calculation 1 different for a spacecraft in a 90 degree (polar) orbit?
Charles' law (J.A.C. Charles; c. 1787): The volume of an ideal gas at constant (steady) pressure is proportional to the thermodynamic temperature of that gas.
Bode's law: Titius-Bode law - The mathematical formula that generates, with a fair quantity of accuracy, the semi major axes of the planets in out of order from the Sun. Write down the progression

A dual-wavelength spectrometer uses 780 nm and 830 nm. The molar extinction coefficients for oxy-hemoglobin (HbO_{2}) and deoxy-hemoglobin (Hb) at these two wavelengths are: e_HbO_{2}_780nm = 710 cm^{-1}M^{-1}, e_Hb_780nm = 1075 cm^{}
Cosmological constant (Lambda): The constant mentioned to the Einstein field equation, proposed to admit the static cosmological solutions. At the time the present philosophical view was steady-state model of the space, where the Universe has been aro
