    1 day ago · This experiment involves diffraction of light waves though a very small slit (aperture), and demonstrate that when light passes through the slit, the physical size of the slit determines how the slit interacts with the light.

    5 days ago · In a dispersive prism, material dispersion (a wavelength -dependent refractive index) causes different colors to refract at different angles, splitting white light into a spectrum. 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 ...

    2 days ago · When light travels from a denser to rarer medium with an angle greater than the critical angle, the ray of light does not deviate in its path or does not refract, but it undergoes a reflection known as total internal reflection.

    2 days ago · Geometrical optics deals with the propagation of light in a straight line and phenomena such as reflection, refraction, polarization, etc. A ray of light gives the direction of propagation of light. In the absence of an obstacle, the rays advance in a straight line without changing direction.

    5 days ago · In this explainer, we will learn how to draw diagrams of light rays interacting with convex lenses. A convex lens focuses parallel light rays at a focal point. This is shown in the following figure. The directions of light rays that pass through the lens depend on two rules.

    3 days ago · Light rays are not opaque, at least not significantly, so it is usually an additive effect. Try chaning the blend mode selection from add to over/merge (whatever the name is, can't try at the moment) and see if you get something in alpha.
