Ultraviolet (UV) radiation is similar to visible light in all physical aspects, except that it does not enable us to see things. The light that enables us to see things is referred to as visible light and is composed of the colors we see in a rainbow.
Playing Regulations. A game of basketball is made up of four quarters, each ten (or in the National Basketball Association 12,) minutes long. At the start of every game the referee throws the basketball up in the air, and one player from each team tries to hit it to their teammates, that is called a jump ball..
i think the actual time for all 4 quarters is 48 minutes 12 each but in halftime it takes a while too so it all adds up to around 2 and a half hours long and foul shots don t take time off the clock either an average nba basketball game last at least an hour to 2 hours i hope that answred your question
