Document Summary
5. 1 light travels through empty space at a speed of 300,000 km/s. The speed of light in a vacuum is a universal constant: it has the same value everywhere in the cosmos. Galileo and isaac newton asked basic questions about light. Olaus romer first evidence that light does not travel instantaneously. Armand-hippolyte fizeau and jean foucault method of measuring the speed of light using deflection angle. Speed of light same throughout univers c=3. 00e8 m/s. According to einstein"s special theory of relativity, there is a universal speed limit: nothing can travel faster than the speed of light. 5. 2 light is electromagnetic radiation and is characterized by its. Visible light, radio waves, and x-rays are all the same type of wave: they differ only in their wavelength. Prism separates colours and does not add. Suggested light made of small particles, christian huygens proposed light travels in the form of waves. Maxwell and light as an electromagnetic field.
