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.

In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
so we just started physics in grade 10, and i dont understand to much of it.. could you help me better understand it? and help me understand what i should expect?
Mention two salient features of immunity theory of ageing. Write the full form of ESR. What does the increase in ESR indicate?
