A medium is known as denser if the velocity of ray in that phase is fewer than the speed of the wave in other phase.
In comparison to air velocity of sound is main in water, as water is rarer phase for sound waves w.r.t. air. But it is not right for light (EM-waves). For light rays water is denser medium w.r.t. air.
Q What is Tyndal scattering? Tyndal scattering- When light passes throughout a colloidal solution its path is visible inside the solution. This is for the reason that the
Inductors in dc circuits: If it is required to increases the value of inductance in a circuit, then two or more inductors may be connected in series. The total inductance then

Consider charge of consistent surface density (charge-per-area) everywhere on an infinite horizontal plane. In computing the electric field due to such a charge distribution one ca
Could the light along a side emitting optic be a totally homogeneous? Regardless of the assurances of several manufacturers, it is a total impossibility since it would clash wi
A satellite of mass "M" is in orbit around the earth. If a second satellite of mass "2M" is to be placed in the same orbit, the second satellite must have a velocity which is:
