Apr 13, 2023 · When light from the sun or a table lamp hits the ball, the ball bounces some light rays directly into your eyes, while it bounces other rays off into the mirror. The mirror reflects those light rays, in straight lines, at the same angle—and some of them end up in your eyes (red line).
If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of reflection.
The mirrors condense lots of light from faint sources in space onto a much smaller viewing area and allow the viewer to see far away objects and events in space that would be invisible to the naked eye. Light rays travel towards the mirror in a straight line and are reflected inwards to meet at a point called the focal point.
Oct 2, 2014 · In a reflecting telescope, light strikes the primary mirror and bounces back to a secondary mirror, which diverts the light to the lens in the eyepiece.
Nov 14, 2024 · reflection of light in a mirror According to the law of reflection, images are reflected from a smooth surface, such as a mirror, at the same angle (θ2) as the incidence angle (θ1).
Feb 4, 2016 · Key to the way a mirror functions is how the physics of light behave in our Universe: the same laws that make a banana appear yellow and a piece of paper appear white. The colour of something is defined by which colours of the visible spectrum it absorbs or reflects.
With a smooth surface, light reflects without disturbing the incoming image. This is called specular reflection. That concept raises an interesting question: If mirrors preserve the images that hit them, why do they turn left into right and vice versa? Why not up and down? The truth is that a mirror doesn't really reverse left and right.
