Which of the pictured is responsible for black pavement being hot?

• Transmission

• Reflection

• Refraction

• Scattering

• Absorption

According to the data, which media does light travel fastest through?

• 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.

Which two media does light waves travel the same in?

• 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.

Light waves travels fastest through the air because air is a gas, which means it is less dense than the other media, which are solids and liquids.

• true

• false

Light travels slower in the Perspex than in the water because Perspex is more dense than the water, meaning it has more molecules that are attempting the block the light waves from passing through.

• True

• False
