The warmth you feel come from the Infrared rays.
cuz crack in a glass means there wud be a layer of air in the crack.thus when light rays muv 4m glass to air that is denser to rarer medium,as we all knw, Total internal reflection occurs.as a result,light rays get refleted to our eyes,so a shine seems to appear on d crack.
A warm front is the type of front where warm air is lifted over a mass of cooler, denser air at the surface. This lifting action leads to the warm air being unable to move forward and being cut off from the ground by the cool air beneath it.
For painting on glass, use glass paint or enamel paint specifically designed for glass surfaces. These paints are durable, waterproof, and will not wash off glass surfaces even with exposure to water or soap. Be sure to follow the manufacturer's instructions for application and curing to ensure it adheres properly to the glass.
The three types of radiation given off by radioactive substances are alpha particles, beta particles, and gamma rays. Alpha particles are the least penetrating, beta particles are more penetrating than alpha particles, and gamma rays are the most penetrating and dangerous type of radiation.
If light rays do not enter a glass block, they will continue to travel in their original direction. The glass block will have no effect on the path of the light rays unless they actually enter the block.
You would need to know exactly what type off window you have that was broken. With some window frames it can be as simple as removing the broken glass, picking up a new cut-to-measure pane at Lowes or a local glass shop and putting the new glass in. With other systems it may be more complicated. There are glass contractors in all cities that specialize in this type off thing, if you would rather not do it yourself.
Bent light rays. Note - you never actually "see" an object, just the light reflecting off it.
Ammonia. That will cut through the grease and clean the window.
To cut the bottom off a glass bottle effectively, you can use a glass cutter to score a line around the bottle where you want to cut it. Then, carefully heat the scored line with a candle or a heat source. After heating, quickly cool the bottle with cold water. The thermal shock will cause the bottle to break cleanly along the scored line.
Light rays bounce off of smooth and polished surfaces, such as mirrors or glass, with a regular reflecting pattern. These surfaces reflect light at predictable angles based on the law of reflection.
To cut glass bottles in half, you need a specialized glass cutting tool designed for bottles to score the glass, then you tap it repeatedly until a crack follows the scoring separating the bottle in two. You will also need to grind off the sharp edges to prevent someone getting cut.
Use a glass cutter to cut the bottle top off the bottle, use sandpaper to smooth the edges of the glass.
To safely cut the bottom off a glass bottle, you can use a glass cutter tool to score a line around the bottle where you want to cut it. Then, carefully pour boiling water over the score line, followed by cold water. The sudden change in temperature should cause the bottle to break cleanly along the scored line. Remember to wear protective gloves and eyewear while handling the glass.
Avulsion
it gives of rays of very explosive light if it touches you, you will die instantly and your guts will fly everywhere
Diamonds have a high refractive index--which means they can really bend light rays. So light rays that shine into them will stay inside the diamond longer than they would inside glass, plastic, or any other material with a lower refractive index. And diamonds are cut to maximize this light capturing effect. All those sides and angles are carefully designed to keep incoming rays inside a long time--by making them bounce off as many walls as possible.Diamonds have a high refractive index--which means they can really bend light rays.
