Em wave - Study guides, Revision notes & Summaries

What is the speed of light? - Light can travel enormous distances under short periods of time. It is faster than any other phenomenon. It takes about 8 minutes for light to travel from the Sun to Earth. The speed of light in a vacuum is c=3x10^8 m/s. Why is light such an important tool for astronomers? - Because light is how we learn about distant objects without travelling there. It is also a measuring took of astronomy. Light is a wave and a particle. How are different kinds of light wave...
