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.
what is the physical significance of damping coefficient?
A battery and the plug points in the switch boards home give potential difference. What is the disimilar in the nature of the current given by the two? Compare and contrast the tw
