Bending the light - physics experiment
Bending the light - physics experiment
http://www.fizik.si This is an interesting experiment to show the total internal reflection. We get the total reflection if the light enters to an optical less dense material and the incidence angle is big enough. The incidence angle at which the ray refracts exactly along the boundary line, is cal...

Total internal reflection breakdown - Science experiment
http://www.fizik.si When light passes from a medium with one index of refraction (M1) to another medium with a lower index of refraction (M2), it bends or refracts away from an imaginary line perpendicular to the surface (normal line). As the angle of the beam through M1 becomes greater with respect...

Polarization - Science experiment
Polarization - Science experiment
http://www.fizik.si Polaroid filters are made of a special material which is capable of blocking one of the two planes of vibration of an electromagnetic wave. In this sense, a Polaroid serves as a device which filters out one-half of the vibrations upon transmission of the light through the filter....

Refraction - Science experiment
http://www.fizik.si Refraction occurs when light waves travel from a medium with a given refractive index to a medium with another at an angle. At the boundary between the media, the wave's phase velocity is altered, usually causing a change in direction.
