• It is the only light that can travel through solids.

• It is the only light that can travel through air.

Where did most eyes first evolve?

• On land

• In space

• In the air

• In water

How is visible light created at the microscopic level?

• When a proton gains energy

• When a neutron drops to a lower energy state

• When an electron gains energy

• When an electron drops to a lower energy state

What creates an oscillating magnetic field at the macroscopic level?

• A moving proton

• A moving electron

• A moving neutron

• A moving photon

What is the speed of light in a vacuum?

Why is the speed of light finite?

• It is unknown

• Due to the properties of space
