(a) State the postulate of STR and deduce Lorentz Transformation.
OR
Give basic postulate of special theory of relativity. Derive Lorentz Transformation equations.
(b) Prove that particle having rest mass zero is always moving with velocity of light.
Q. Find the minimum wavelength of X-rays produced by an X-ray tube operating at 1000 kV. λmin = 12400 A 0 / V Therefore λmin = 12400 X 10 -10 / 10 6 = 0.0124 A 0
Q. Illustrate What is the geocentric? Answer:- It is science where the earth is the midpoint of the solar system and the other planets and the sun revolve around the earth
An atom in a solid state has no degrees of freedom for transnational and rotational speed. At great temperatures due to vibration along 3 axes it has 3 Χ2(directions) = 6 degrees
What do you mean by thermal neutron? What is its importance? What do you mean by annihilation of matter? Given an example
what, why, use
Prism is a transparent phase rounded by refracting surfaces, like the incident surface and emergent surface (from which light rays emerges) are plane and non parallel
Derivation
Brewster's law (D. Brewster) The extent of the polarization of light reflected through a transparent surface is maximum while the reflected ray is at right angles to the refra
On transitory from a medium with one index of refraction to a medium with a different index of refraction light is typically both reflected and refracted. Under some conditions how
VARIABLE OR NON-UNIFORM VELOCITY: If a body covers unequal displacement in most equal intervals of time, though the smallest interval may be, then the velocity of the body is s
