WebJul 21, 2016 · When light (composed of photons with different frequency and wavelength) falls on a material, some of it gets absorbed and some get reflected depending upon the color of the material on which it strikes. And the material reflects the light of its own color only, thereby absorbing all the other colored light. So, my questions are: WebFeb 14, 2024 · Why do we see the road, or a pen, or a best friend?

WebAnswer 2: Mirrors reflect mainly because they are electrically conductive. Light is an electromagnetic field, and when it hits a mirror the metal inside of it (usually aluminum or silver) cancels out the electric field parallel to the mirror which causes it to change directions and reflect away. WebEmmetropia is the term used to describe an eye without any refractive errors. The axial length of the eye, the distance from the posterior cornea to the surface of the retina, is equal to the focal length of the eye. Two … how much potassium in tahini sauce

During reflection does the emitted photon have same properties?

WebReflection doesn't involve photons being absorbed then re-emitted. You're correct that the oscillating light wave of the light interacts with electrons in the reflector, and the resulting oscillating dipoles reradiate light. However, while this is easily described using a wave model it's hard to describe using photons. WebLight just keeps going and going until it bumps into something. Then it can either be reflected or absorbed. Astronomers have detected some light that has been traveling for more that 12 billion years, close to the age of the universe. Light has some interesting properties. It comes in lumps called photons. WebWhy does light sometimes get reflected, and is sometimes allowed through glass? I was playing with my laser, and shining it upon my glass table. There was a spot of light on the point of incidence, there there was a beam of the laser that went through the glass table and fell on the floor which is normal since glass is transparent. how do lift stations work in a sewer system

WebMay 5, 2016 · As light passes through air and into another clear material (such as glass), it changes speed, and light is both reflected and refracted by the glass. This results in us … WebObjects appear colored because of the way they reflect light. Sunlight is a mixture of all colors of light, which combine to form brilliant white light. Some surfaces reflect all of this light, while others absorb some of the colors. A white ball looks that way because it reflects all of the light that hits it.

WebWhether a sound wave is reflected, refracted, or absorbed depends on the densities of the materials either side of the boundary. If the densities are very different then reflection is … WebThe ray of light that leaves the mirror is known as the reflected ray (labeled R in the diagram). At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is …

WebLight reflected off a lake is partially polarized in a direction parallel to the water's surface. Fishermen know that the use of glare-reducing sunglasses with the proper polarization axis allows for the blocking of this partially polarized light. By blocking the plane-polarized light, the glare is reduced and the fisherman can more easily see ... Webthe angle of reflection, r, is the angle between the normal and reflected ray. The law of reflection states that the angle of incidence equals the angle of reflection, i = r. It works for any ...

WebOct 2, 2014 · In a Newtonian reflecting telescope, light rays from distant objects, which are essentially parallel (because they come from so far away), strike the concave main mirror at the same angle.
