Laws of Refraction:
There are two laws of refraction.
The incident ray, the refracted ray and the normal to the surface of the point of incidence all lie at the similar plane.
The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing from single medium to another medium. This constant is known as refractive index.
Q. Explain how Compton scattering confirms the quantum nature of radiation. OR What is "Compton Effect"? Deduce an expression for shift in wavelength of scattered X ray
Q. Find the electric potential at a distance 0.09 m from a charge of 4 X 10 -7 C. The electric potential V = ( 1/4πεo ) q /r = ( 9 X 10 9 X 4 X 10 -7 )/ 9 X 10 -2 = 4 X 10
What is force
(1) Melting point : 936 0 C (2) Atomic number : 32 (3) Energy gap : 0.6ev (4) It is a gray metallic looking mat
Q. What is the dissimilarity between electric potential and electric potential energy? Ans: Suppose you desire to know the electric potential energy that a particular part
in water equivalent how the temperature or water and solid equal?
Electric Field: The electrical field because of a charge can be described as the space around the charge.
Direct Current (DC): Such a current can be getting by connecting the two ends of a conductor to the terminals of the battery. This current doesn't change the direction
