(i)Most of the alpha-particles pass by the foil straight away undeflected.
(ii)Some of them are deflected by small angles.
(iii)A few alpha-particles (1 in 1000) are deflected by the angle more than 90o.
(iv)A few alpha -particles (very few) returned back i.e. deflected by 180o.
(v) Distance of closest approach (Nuclear dimension)
After Rutherford's scattering of alpha-particles experiment, following conclusions were made as regard as atomic structure:
(a) Most of the volume and every of the charge of an atom concentrated in a very minute region is known as atomic nucleus.
(b) Nucleus has positive charge and it's size is of the order of 10–15 m ≈1 Fermi.
(c) In a molecule there is maximum empty space and the electrons revolve around the nucleus in the similar way as the planets revolve around the sun.

Your friend has gifted an earphone set to you. While music is on you will try to oppose the two ear phone pieces to attract. Task-I: Will they attract? If yes, why so?
Cosmological redshift An effect where light emitted through a distant source seems redshifted due to the expansion of spacetime itself.
Mass energy relation - The total energy of a body is the sum of its kinetic energy and rest mass energy. Particle having rest mass zero always move with the velocity of light.
Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called
