occurs when light strikes a surface with microscopic irregularities or roughness. These imperfections cause the light to bounce off in different directions instead of reflecting at a single angle. As a result, the light is scattered and diffused, creating a more even distribution of reflected light...
In reflection, a light ray strikes a smooth surface, such as a mirror, and bounces off. A reflected ray always comes off the surface of a material at an angle equal to the angle at which the incoming ray hit the surface. In physics, you'll hear this called the law of reflection. Yo...
In the most common type of mirage, an object appears to be reflected as if there were a pool of water on the ground. This phenomenon is caused by light refraction — the bending of light beams.Lightbends when it passes from one medium into another — from air to water, for example, o...
“For example, if someone is interested in DIY and wants to grind wood with sandpaper, they’ll likely choose a coarser option first as that will result in quicker progress. They will then be left with a rough surface, so they’ll probably opt for a finer grade that will give them a ...
Governing the physical and chemical characteristics of contact area among solid substrate and liquid droplets is a widely used strategy to fabricate superhydrophobic and superhydrophilic surfaces. While both surface morphology and surface free energy of a solid substrate conclude its wettability, designing ...
You will need to allow the wood fence to dry before moving on to the next step. The following video is specifically about how to clean and prep a wooden deck, however it is also very relevant to how you can clean a fence for staining. ...
After those five months, I not only don’t miss cooking with gas but have been reminded of what I don’t miss when I’ve used other people’s gas stovetops where some burners don’t light up reliably. But it’s also easy for me to say that when we still have a gas grill on th...
Are the surface flows on privately owned lands? If the lava is outside of the park boundaries there is a good chance it is on privately owned lands and that you will be trespassing while hiking out. Make sure to get proper permission from the land owners before hiking up to these spots...
When the brightness of the direct or reflected light gets to about 4,000 lumens, our eyes begin to have difficulty absorbing the light. What we see when we try to look at these brighter areas are flashes of white -- this is glare. To reduce the discomfort caused by the amount of ...
Once the epoxy has cured, use a block plane or power sander to trim the keys flush to the slab surface. Then sand smooth. Space keys along the crack's length in proportion to the slab size. Install keys on both faces to further protect against future splits; they don't need to align...
