One long-legged spider is the "daddy long-legs" (cellar Spiders, family Pholcidae) but they are not known to "bounce." If it is bobbing up and down, it may be a similar, harmless arachnid called a "harvestman."

I use toward but sometimes it depends on your accent
It stops stuff from flying into your eyes for example when shooting a gun in case a bullet bounces off the target and back toward your face.
The Redcoats
Medium A is the more optically dense medium. As when the light enters B its speed increases taking it toward the normal.
silly silly... hobo? its called stray (st-ray) well the spider waits at the end of its cobweb. then aha! the bug gets trapped it cant escape! the spider walks toward it. then he cocoon's the bug. were only it's head shows. then SNAP the spider eats the bug. yummy

Comets come toward earth during their orbits. They are drawn toward the sun by gravity and sometimes cross earth's orbital path in the process.
He was constantly blowing it, he was what is sometimes called a spendthrift.
Sound disturbance is propagated by compressions and rarefactions through the air medium. Air is a material medium. If such a material medium is absent then sound waves cannot be propagated. These compressions and rarefactions confirm that the wave is of longitudinal in nature.
This spider more than likely is an Argiope, this is a common spider than can be found all over the world. If you seen the web, this spider is known to spin a white zigzag pattern on their web.
The refractive index of air is about 1.0003, and of quartz about 1.45, so quartz is the more "optically dense" medium in this situation. When light goes from a less dense medium to a more dense medium, it is refracted toward the normal. The normal is the imaginary line perpendicular to the surface where the light enters.
