What causes reflection of light?
Light is reflected when there is a mismatch between materials through which the light is travelling. Normally the index of refraction is used to determine the angle that light propagates in a material when it “bends” or refracts, but we can also use it to calculate how much light reflects.
Why is light reflected off a mirror?
When photons — rays of light — coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image. If a smooth surface absorbs the photons, they can’t bounce back and there will be no reflection.
Why are there things that are reflective and non reflective?
Things reflect because of a combination of things, including their refractive index, how smooth the surface is, and finally, in the case of metals, and mirrors, because there are electrons in the material that are free. The scientific term for this is refraction, and water has a higher refractive index than air.

What is the difference between reflected light and incident light?
In other words, it’s the light that bounces, or reflects, off the presence of reflective materials in your scene. In summary, an incident meter measures the light that is illuminating your subject, whereas a reflected light meter measures the light that is reflecting from your subject.
Why do shiny objects reflect light?
Shiny objects reflect most light that hits them in a particular direction. than shiny objects as they absorb some of the light energy. Their surfaces are less smooth than those of shiny objects, so the light they reflect scatters in all directions. In each part of its ‘journey’ the light travelled in a straight line.
Why do you see your image in a mirror?
An image can be seen in the mirror because the light reflected from an object falls on the mirror and it is reflected. So, light incident on any smooth shiny surface like a mirror bounces back into the same medium. This bouncing of light by any smooth surface is called reflection of light.
Is Rainbow a refraction?
Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave’s direction. A refracted wave may appear “bent”, while a reflected wave might seem to “bounce back” from a surface or other wavefront. Rainbows are actually full circles.
