Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.
Which of the following is the best example of this transfer of energy?
(1 point)
heated air rising through the atmosphere
volcanic lava heating the ground it touches
sunlight warming sand at the beach
ocean currents arising from temperature differences
