Define Ergosphere
Ergosphere: The area around a rotating black hole, among the event horizon and the static limit, where the rotational energy can be removed from the black hole.
What do you mean by the term Newton meter? Explain briefly?

Bragg's law - Whenever a beam of x-rays strikes a crystal surface in which the layers of ions or atoms are often separated, the maximum intensity of the reflected ray takes place when the complement of the angle of incidence, theta (θ), the wave
What is the reason that heat causes matter to expand? Briefly explain it.

What do you mean by the term wave fronts? Explain in short.
Chandrasekhar limit (S. Chandrasekhar; 1930): A limit that mandates that no white dwarf (a collapsed, degenerate star) can be much massive than around 1.4 masses solar. Any of the degenerate mass more massive should inevitably collaps
Tardon: A particle that has a positive real mass and travels at a speed very less than c in all inertial frames.
Event horizon: The radius which a spherical mass should be compressed to in order to convert it into a black hole, or the radius at which the time and space switch responsibilities. Once within the event horizon, it is basically impossible to escape t
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
