light always travels in straight lines,but ut sometimes bends when traveling through differnt mediums.?

Question

What is that called?

Answer 1

refraction

Answer 2

Light travels in every direction at once, and it follows the contours of space/time, where space is curved by the presence of gravity. Refraction is the change in direction of a wave due to a change in its speed. This is most commonly seen when a wave passes from one medium to another. Refraction of light is the most commonly seen example, but any type of wave can refract when it interacts with a medium, for example when sound waves pass from one medium into another.

Answer 3

its 'refraction' the most common type of natural refraction is a rainbow when white light from the sun is refracted or 'bent' as is passes through the rainwater. different colour light bends at diferent angles so it gets split into its component parts

Answer 4

All you are able to desire to do is rememeber that mild is a wave. between the homes of waves is they are going to shuttle at diverse speeds with the aid of diverse media or extra precisely, matter with diverse densities. The bending you be conscious is as a results of the interface of one fabric, (air, glass, plastic, polycarbonates, etc) with yet another diverse fabric. on the interface, the mild particularly variations speed, swifter in much less dense stuff, slower in extra advantageous density stuff. ok, say you have a beam of sunshine. ok, Now it particularly is my feeble attempt at equating this to something extra advantageous... Say you're making use of a vehicle at a relentless potential (not speed!). you canpersistent somewhat speedy on the pavement, which has a severe density. The gentle sand on the side of the line is extremely stressful to go speedy in. So let's imagine you swerve off the line and your left tires hit the sand... they are going to at present decelerate, however the appropriate side will nevertheless be going speedy on the pavement. the effect it which you finally finally end up turning onto the sand. as quickly as all 4 tires are on the sand, there is not extra jerk that takes the steerage because of the fact all the wheels are on an analogous media. Now say you probably did not suited your course after happening the sand, and there is yet another stretch of pavement springing up it particularly is parallel to the only you have been in simple terms on. Your left tires hit the line first, capture some sturdy traction and take off, collectively as the appropriate side continues to be sluggish interior the sand. the effect? the vehicle is heading interior the right comparable course (in basic terms on a parallel) as once you left the 1st highway. Now faux the vehicle is a mild beam, the sandy area in between the roads is glass, and the roads themselves are a vacuum. In a vacuum, the fee of sunshine is approximately 3 hundred,000,000 M/Sec. while coming near from an attitude, because it hits the interface on the glass, the leading side slows down (the fee of sunshine in glass is type of seventy 5% of a vacuum) and the trailing side continues to be on an analogous speed. This outcomes interior the bend you spot. while the mild hits the different side of the glass, it particularly is going to opposite that action, speed up lower back and the beam will now be traveling alongside a parallel course. This replace right into slightly longer than I estimated yet with a bit of luck it helps you already know what is going on. :)
