A sound wave is very low frequency as it starts off on the Wave spectrum, You can tell if the frequency is low or high by the wavelength.

the wavelength is how wide the wave is from crest to crest (crest: the top of the wave)

If the wavelength is very long, it means that there is low frequency, the closer the crests are the higher frequency there is throughout the wave!

So sound waves are much less frequent or concentrated, than Electromagnetic waves.

If you don't understand this, go look at some pictures of the wave spectrum. It should help a bit!

A sound wave is a mechanical wave and cannot travel through empty space. It needs to travel through a medium of some kind. To remember this, the saying "no one can hear you scream in space" is somewhat helpful considering sound waves cannot travel through an empty vacuum like such. An electromagnetic wave ( EM wave ) does not need a medium to travel and can travel freely through empty space.

Write an essay on basketball history and how the game has changed over time
jarptica [38.1K]

Basket ball has gone through some changes and hence got into shape as what we play or watch nowadays. Overall rules have the same fundamental principles as set in 1891 by the founder of this game.

December 21st, in 1891, the introductory basketball game was played in Springfield, Massachusetts. It was first brought into shape by a Canadian-by birth, Dr. James Naismith. The basic idea of the new game was to keep the sports loving students in shape during the winters or in between the outdoor game seasons.

'The basket ball' which had a set of thirteen basic rules set up a strong foundation to the game and still played almost in the same style with few modifications.In the very year of 1891, after mixing and changing theme of several other played games of those days, basket ball was born.

Initially, basket ball with the 13 rules was played with 2 peach baskets setup as goals, which now a days are the baskets on a high poles although modified but with same basic idea. In the very first game played in Springfield, the set of players were able to score a single point only, in the whole game.

By comparing Naismith’s basketball and basketball of today we see a characteristic of the original game which had no dribbling, instead a player had to pass the ball to a another player of his team ,from his the very spot where he caught it. The second thing which has now changed is the fouls, in the original game if any team made 3 consecutive foul play ,the oponent received a goal in reward. Although this scoring technique doesn't exist in the modern basketball. Rather nowadays, if any team makes five fouls in one quarter, the offending team is in the penalty ,and shoot free throws are awarded against them.

All other rules are quiet intact in the modern play as well. As the game today,has extended to over 2 hundered countries and enjoyed by many on television screens, with modern umpiring and technologies being used in the game, but the original idea of the founder is still endured.
