When sound waves travel from a rarer medium to a denser medium, its speed
decreases
remain constant
increases
may increase or decrease
Speed of sound is inversely proportional to the density of the medium.
When sound waves travel from a rarer medium to a denser medium, its speed:
When sound waves travel from a rarer gaseous medium to a denser gaseous medium, its speed __.
When light travels from rarer to denser medium,speed decreases, and when it comes out from denser medium speed increases...we know that if a body changes its speed or acceleration.. force needs to be applied...so which force makes it to speed up or slow down..while going through denser to rarer...which force acts on it to increase the speed???
