Watch the video above on how you can create your own elephant toothpaste. Experimental is a new AOL.com original series that demonstrates simple science experiments for adults and children to do ...
Elephant's toothpaste. Elephant toothpaste reaction. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide ( H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. [ 1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. [ 2][ 3][ 4]
Prism (optics) A familiar dispersive prism. An optical prism is a transparent optical element with flat, polished surfaces that are designed to refract light. At least one surface must be angled — elements with two parallel surfaces are not prisms. The most familiar type of optical prism is the triangular prism, which has a triangular base ...
Dispersive prism. In optics, a dispersive prism is an optical prism that is used to disperse light, that is, to separate light into its spectral components (the colors of the rainbow ). Different wavelengths (colors) of light will be deflected by the prism at different angles. [ 1] This is a result of the prism material's index of refraction ...
Opticks: or, A Treatise of the Reflexions, Refractions, Inflexions and Colours of Light is a collection of three books by Isaac Newton that was published in English in 1704 (a scholarly Latin translation appeared in 1706). [ 1] The treatise analyzes the fundamental nature of light by means of the refraction of light with prisms and lenses, the ...
A compact fluorescent lamp seen through an Amici prism. In optics and in wave propagation in general, dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency; [ 1] sometimes the term chromatic dispersion is used for specificity to optics in particular. A medium having this common property may be termed a ...
The 18-year-old, who is known to be quite the animated character while playing video games, decided to go live on 3 October to show fans the “elephant toothpaste” experiment.
In modern physics, the double-slit experiment demonstrates that light and matter can satisfy the seemingly incongruous classical definitions for both waves and particles. This ambiguity is considered evidence for the fundamentally probabilistic nature of quantum mechanics. This type of experiment was first performed by Thomas Young in 1801, as ...
