Expert Answer
Wave needs a medium to propagate to transfer the energy as waves is formed by transfer of energy in particles (also said as disturbance in medium. Light waves are said to be propagated in the medium "ether".
"Waves travel faster in denser medium" is the property of sound waves not light waves.
