Excellent explanation. It's like going through Newton's head. I wish all professors taught in this manner, following the logic of the founder/discoverer.

i could follow up to the last prism with last prism i mean the prism being at the focal point for the light sure the ray has a different entrace angle and i know that effects the outgoing angle as snails law describe but still the last prism has 2 area´s that are bend (out and in) why the result is still white ?

The answer is cheese

This platform let us spread all we know about the field and from MEETOPTICS we are proud to be part of the photonics community and to help engineers and researchers in their search for optical lenses through our site, from prisms to mirrors and fresnel lenses.

My Icon...

is the prism dispersing the light and if so how? is this anything to do with refraction but not diffraction? is diffraction more about interference of the light with itself?

MIT

Thank you so much for your succinct and articulate explanation. I'm having trouble understanding a certain principle though, which I hope someone could explain. How can you effectively create 'white light' by combining 2 prisms and a lens? Are you merely mimicking the input light? How does is work? Are you essentially splitting the constituent wavelengths via dispersion, then 'focusing' or 'combining' them again? I can't quite understand how (just from a fairly basic standpoint). Thank you

@arandombeing7262

Жыл бұрын

Focusing and combining is the same thing as far as i can think, in this case atleast. The RGB colors just need to be close enough to be *percieved* as white by your eye. They were close in intial ray and in the final ray too so we see white color in both these cases and they where seperated in the middle.

@arandombeing7262

Жыл бұрын

And this explanation makes sense bcz we know that their is no such thing as 'white light', white light is just a mix of different colors that OUR BRAIN THINKS IS WHITE. This can be proven by experiments like these and more convincingly using a spinning rainbow wheel.

Which type of glasses we can use for dispersion of light

Hi, where can I buy a concave lens that stands on its own, such as the one seen in this video? (Or is there a simple way to make one in a mold?)

How did you get that focussed white light source? I am looking to decorate my bedroom wall with something like this. Rather than putting a poster of a prism on the wall I am thinking of putting up the real deal. Sourced the prism. I’m struggling with the light source and getting it to be a narrow white beam. Pin holes on shoe boxes work well but the intensity of the light is terrible.

Excellent video and kudos for the great effort. You nicely explained what is happening. But please explain WHY at all the white light splits into various colors in a prism ? What happens to the white light inside a prism ? Because the same light passing through a glass slab will not split into spectrum. If you could explain it , your video will be 100 % perfect and 100 % appreciable.

@aarushprasad4493

Жыл бұрын

its because the white light passing through is just an overlap of all the colors, and each individual color experiences a different refractive index, therefore spreading out the colors
