What is the difference between reflection and refraction?

When light travels through a medium or from one medium to another, its direction is bound to change, and this change is what forms the basis for the difference between reflection and refraction.

Reflection occurs when the light returns back to its medium of origin after it strikes another medium, without any change in speed. Refraction, however, refers to when the speed and direction of light change when it travels from one medium to the next.

In reflection, light returns after hitting a shiny surface without passing through it, whereas refraction only takes place when light passes through a transparent medium.

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]

Cigarette smoking causes emphysema.

Nearly everyone knows that smoking causes lung cancer, but did you know that smoking causes a number of other serious lung diseases?
