Speed of Waves in Media AKS 9D

Air because it has the highest refractive index which means it is the most dense. The denser a medium is the faster the light wave will travel.

Air because it has the lowest refractive index which means it is the least dense. The less dense a medium, the faster the light wave will travel.

Diamond because it has the lowest refractive index which means it is the least dense, which means the wave will move the fastest.

Diamond because it has the highest refractive index which means it is the most dense. The denser a medium is the faster the light wave will travel.

Air and Water because it travels at 300,000,000 m/s through these media.

Water and Perspex because it travels at 230,000,000 m/s through these media.

Perspex and Glass because it travels at 230,000,000 m/s through the media.

Glass and Diamond because it travels at 242,000,000 m/s through the media.

the temperature is 68 degrees, which means the molecules are able to transfer the waves faster.

the temperature is 32 degrees, which means the molecules are able to transfer the waves faster.

the temperature is always the same for air, so the temperature does not make a difference

air is a gas that is spread out and allows the sound waves to travel through it faster
