Why can human ears hear dolphins' vocalizations while under the water but cannot hear them well on land?

• The waves in the water travel faster and at a higher frequency than they travel on land.

• The waves in the water travel faster and at a lower frequency than they travel on land.

• The waves in the water travel slower and at a higher frequency than they travel on land.

• The waves in the water travel slower and at a lower frequency than they travel on land.

How is the light wave that travels through a prism refracted when the Sun's radiation reaches Earth?

• The light reflect off the surface of the prism.

• The light is absorbed by the glass in the prism.

• The light speeds up as it leaves the prism and enters the air.

• The light slows down as it moves from the air into the glass.
