In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye.  Which statement is true regarding the light wave as it travels?

• It will bend as it hits the water because it slows down

• it will bend as it hits the water because the water particles move slower than air

• it will travel straight from the bug to the fishes' eye because that is the most direct path

• it will travel straight from the bug to the fishes' eye because it will continue to travel at the speed of light
