How does solar energy travel?

Answer 1

Ever since Democritus - a Greek philosopher who lived between the 5th and 4th century's BCE - argued that all of existence was made up of tiny indivisible atoms, scientists have been speculating as to the true nature of light. Whereas scientists ventured back and forth between the notion that light was a particle or a wave until the modern, the 20th century led to breakthroughs that showed that it behaves as both.

These included the discovery of the electron, the development of quantum theory, and Einstein's Theory of Relativity. However, there remains many fascinating and unanswered questions when it comes to light, many of which arise from its dual nature. For instance, how is it that light can be apparently without mass, but still behave as a particle? And how can it behave like a wave and pass through a vacuum, when all other waves require a medium to propagate?

Answer 2

The speed of light in space is about 300000 Km per second

(About 186,000 miles per second)
Sunlight is "light" of course, and hence travels 186,000 miles per second in a vacuum.

Answer 3

it travels like radio waves but as light, and is in the form of ultraviolet rays.
