WebIn contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because … WebAug 21, 2024 · The rays of light converge at the focal point. At this point they again begin to diverge. A second convex lens in the eyepiece takes the converging light and straightens it back out. This magnifies the image at the focal point and brings it into focus. Because of this, a refractor has to have a long, clear path to allow the light rays to bend. irctc rail fare chart

WebLight travels in straight lines, so if you have to represent a ray of light in a drawing, always use a ruler. Unlike sound waves, light waves can travel through a vacuum (empty space).... WebBlurt. vijanti dhanji answered. When a ray of light travels from one medium to another, it is bent and so travels in a new direction. The light is said to have been refracted, and the bending of light is called refraction. Refraction occurs when light travels from one medium to another and takes place at the boundary of the two media.
