Works on refraction and refractive index being matched.
When the refractive index is the same it reverses the changes in the light pathway and it goes!

Refraction and Reflection of Laser Light

This is a simple video to show the principle of the refraction of light and also the reflection of light using laser monochromatic light. You can clearly see that the ...light changes direction inside the prism or slows down. This is the idea of "refraction". It turns in towards the normal then away as it exits. The pathway is a constant refraction as the density is even throughout. This is not always the case for example in water the pressure changes cause curved refraction, as it the same effect with seismic waves travelling through the Earth. Interesting as well to see something which students often miss as the reflected ray on the surface of the block or the TIR or totally internally reflected rays from the internal surface of the prism.[+] Show More

This demo shows how you refract light by passing into a denser medium i.e. water. The light slows down so as c is lower than the speed of light the ...wavelength changes (reduces) and it interacts with the medium differently.
Refraction = slowing or speeding up of waves in another medium.
Change of angle can happen when the light enters at an angle which is not at 90 degrees to the normal.[+] Show More

This simple video (not in amazing focus!) gives you a simple method to see how a lens can focus light from a filament on a screen. The best thing is ...to try this in class and you can see the filament turns with the naked eye. My camera phone does not do this well but you can see the method works and the Maths![+] Show More

Wood Green, London.
Making Brighton Rock at sweet factory run by George and Gerry Tell.
M/S of man spreading sugar solution onto large baking tray. He adds blob food ...colouring. He folds the sticky slab and carries it to a machine. The machine mixes the colouring and the sugar solution.
Various shots of two men folding strips of the sugar solution. Looking at the end of the strips we see they are letters of the alphabet. Letters spelling "Brighton Rock" are squashed together and then wrapped in a white sheet of sugar mixture. The slab is several inches high and several metres high - looks like gigantic stick of rock.
Various shots of men stretching and rolling out the slab by hand until it is long and thin enough to be cut into sticks of rock. Various shots of woman cutting long thin tube of rock into portions to be wrapped. FILM ID:1261.04

The circumzenithal arc, CZA, is the most beautiful of all the halos an ethereal spectrum
The CZA is never a complete circle around the zenith, that is the exceptionally rare. ...The light that forms the CZA enters an ice crystal through its flat top face, and exits through a side prism face. The refraction of almost parallel sunlight through what is essentially a 90-degree prism accounts for the wide colour separation and the purity of colour.[+] Show More

We will find the critical angle and refractive index of a perspex block by using a ray box and a protractor.
When the angle of incidence is smaller than the ...critical angle, the ray is refracted. When the angle of incidence is larger than the critical angle, the ray goes through total internal reflection. When the angle of incidence is equal to the critical angle, the ray travels along the boundary of the prism. This is the angle of incidence that we want to note down.
To find the refractive index, you need to do 1/sin(C).

This is a quick video walkthrough of an Edexcel exam question. It is designed so you can look at questions which relate to questions from specific parts of the course.
It ...is taken from a real paper and I have used a real mark scheme which I have adapted for on-screen use. If you listen carefully it will give you a really good idea of what an examiner is looking for.[+] Show More
