## Top best answers to the question «When does light travel in straight line»

• Light travels in the straight line because it does not generally interact with the medium and wherever it interacts it does change its path like when it is entering a different medium with different permeability and permittivity(denser or rarer). This interaction and bending of light is called refraction.

Always!

Now, if we change the cardboard in the previous position so that all the holes are in a straight line, then again we will see the light. Hence, it is clear that light travels in a straight line only. This is one of the main properties of light and it is most commonly known as rectilinear propagation.

Can light travel through a vacuum? The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

The light stops and cannot travel through all three cards. When she arranges the holes in a straight line, the light can travel through. In the second example, a light source is shone onto a shiny...

Light travels in a straight line can be observed by keeping an object in the path of light. In an atmosphere which is bit dusty, we can see light traveling in a straight line. Light emerging from the torch, train and lamps always travel in a straight line. Let us study in detail how does light travel in a straight line.

Untitled Document. In a dusty atmosphere it is sometimes possible to see light travelling and it does appear to be moving in a straight line. The fact that light travels can be demonstrated by putting an object in its path. If the object is opaque the result is a degree of blackness on the other side of it which is due to the absence of the light.

Light travels both in straight lines and through reflection, which is a process in which light enters a prism and bends. Discover how light bends when going ...
