WebIn the visible light, we can also see the sun’s outermost layer – the corona. When the visible light travels through a prism, the visible light gets separated into a spectrum of colours. Red colour has the longest … WebThe speed of light in vacuum is constant and does not depend on characteristics of the wave (e.g. its frequency, polarization, etc). In other words, in vacuum blue and red colored light travel at the same speed c. The propagation of light in a medium involves complex interactions between the wave and the material through which it travels.
