In summer holiday . I had 3 extra lessons. The lessons were about wave .At first , I cannot know more about wave as well. But ~~~~when I had finished my reading ( (web sites)) I know more about wave. It is because there are many interesting radio , funny animations and detailed pictures . They can help me learned move about wave.
In these web sites . I found that wave can classify into 4 parts . They are Water waves , Light wave , sound waves , Electromagnetic waves( Electromagnetic spectrum) .Although teachers had not teach these waves to me, t have already had the concepts of the classification of the waves after I read these web sites. If you ask me the most difficult questions about waves , I will tell you that I don't know . But~~ If you ask me the ordinary questions , I must tell you that I know it certainly. Therefore , I know more about waves than before.
I had seem many Web site (Physics ---Waves) before . All of them are very good , colorful , and knowledgeable.(www.infoline.ru/g23/5495/Physics/English/waves.htm , www.sciencejoywagon.com/physicszone/lesson/09waves/default.htm ,www.gmi.edu/~drussell/Demos.html , http://www.phys.ntu.edu.tw/~cwhuang/pub/phys/ etc )
These web sites are detail enough to tell readers what waves are .For example , They tell us the definition of waves (如果我地學一樣野.但係連果樣野係乜都唔知.咁你好難學嫁) There are many "Daily of Physics" 將生活融入物理.增加 Physics 趣味.For example: When a ship sail in the sea , their bows generate waves . These waves have great resistance to the motion of the ship. Waves with higher amplitude of the waves less energy is required and fuel will be save . This is especially important for cargo ships because they usually travel long distant. 原來平日我地搭船都應用了 Wave . Except this .All of the web sites have animations This animations are made seriously . Especially the stationary waves . I like it very much . I thing this is suitable for very students .
These web sites introduce all kinds of waves ~~~ Water waves , Sound waves , light waves , and electromagnetic waves etc.... Their introductions are detailer than my textbook . I like them very much!!!!
由於這些網頁有中文 and English .看完英文後再看中文, 真係事半功倍ga!!!
加上阿 sir 之前教過部份 Waves ,所以對我做這個報告很有幫助!!!但係其餘既Waves (Water Waves , Sound waves ......) 就冇教過,小弟只好用緊有的領悟力去完成其他部分!!!!*因此尼個報告有D乜野唔好既地方請見諒!!!!*
