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.
Does a piece of glass reflect more light than a piece of paper?

what is the principle operation of this topic?
If two lines of dissimilar metals are connected at their ends so as to form two junctions, then the resulting arrangement is known as a "Thermo couple".

State of Motion: Inertia is the tendency of an object to resist alters in its state of motion. State of motion of an object is described by its velocity - speed with a direc
