Define Newton meter
What do you mean by the term Newton meter? Explain briefly?
Expert
The unit of energy is as well termed as a Joule. Whenever a force of 1 Newton is exerted on an object for a distance of 1 meter, then 1 Joule of energy is utilized. It is the outcome of a vector computation including the meter and the Newton.
It is a unit of torque (that is, turning force). Whenever a force of 1 Newton is exerted at a distance of 1 meter from pivot at right angle to the radius then the torque of 1 Newton Meter is present. This is the metric equivalent of the lb ft.
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.

What do you mean by the rest mass energy of the electron?
Brackett series (Brackett) - The series (or sequence) that explains the emission spectrum of hydrogen whenever the electron is jumping to fourth orbital. All of the lines are in the infrared segment of the spectrum.
Dirac constant: Planck constant, modified form; hbar Sometimes more suitable form of the Planck constant, stated as: hbar = h/(2 pi)
What do you mean by the term alloy? Briefly illustrate it.
Kirchhoff's law of radiation (G.R. Kirchhoff): The emissivity of a body is equivalent to its absorbptance at similar temperature.
Describe briefly the term Specular Reflection?
Spin-orbit effect: The effect that causes atomic energy levels to be split since electrons contain intrinsic angular momentum (that is spin) in summation to their extrinsic orbital angular momentum.
