Contact forces: types of forces that result when the two interacting objects are apparent to be physically linking each other.
Ex: frictional forces, tensional forces, normal forces, air resistant forces, applied forces.
why we use compensater??
How is a wave front dissimilar from a ray ? Draw the geometrical, shape of the wave fronts when (i) light diverges from a point source, and (ii) light emerges out of a convex le
Explain the term 'resolving power' of an astronomical telescope. How does it get affected on 1. Enhancing the aperture of the objective lens? 2. Enhancing the wavelength of t
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
CO has same electrons as or the ion that is isoelectronic with CO is: (1) N + 2 (b) CN - (3) O + 2 (4) O - 2
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
State and illustrate Huygens' principle. Explain the consequences of total internal reflection.
