第一章 声现象 基础知识 1. 一切正在发声的物体都在振动,振动停止,发声也停止。
固体、液体、气体都可以因振动而发出声音。2. 声音传播需要介质(固体、液体、气体)3. 真空不能传播声音,声音以波的形式传播的。
4. 声速与介质的种类和温度有关,一般来说,声音在固体中最快,在液体中较快,在气体中最慢;声音在空气中传播速度为340m╱s5. 听到声音过程:声波—鼓膜振动—听小骨振动—听觉神经—大脑 骨传道:声波—头骨——颌骨—听觉神经—大脑6. 双耳效应:声音到两只耳朵的时间和强弱不同通过双耳效应可以辨别声音的方向,产生立体感。7. 音调指声音的高低。
(1)频率:1秒内振动的次数,反映振动的快慢,物体振动的越快,频率就越大。(2)音调的高低和发声体振动的频率有关系:频率越大,音调越高,频率越低,音调也低。
人的听觉是20Hz---------20000 Hz8. 响度指声音的大小。(1)振幅是物体振动的幅度。
(2)响度跟发声体的振幅有关,振幅越大,响度越大,还跟发声体的距离有关,距离越远,声音就越分散,响度就越小。9. 音色指声音的特色。
音色和发声体的结构、材料有关。10.音调、音色、响度是声音的三要素。
但是,音调高的声音响度不一定大,反之,响度大的声音音调不一定高。11.四大污染:噪声污染、大气污染、水污染、固体废弃物污染。
物理角度来看,噪声是发声体无规则振动时发出的声音。从环保角度看,凡是妨碍人们正常休息,学习和工作的声音,以及对人们要听的声音产生干扰的声音。
11、分贝(dB):表示声音的强弱。0 dB:人刚能听到最微弱的声音。
30—40 dB:较为理想的安静环境,为了保证休息和睡眠,声音不能超过50 dB,为了保证工作和学习,声音不能超过70 dB,为了保护听力,声音不能超过90 dB 。12.控制噪声:在声源处减弱、在传播过程中减弱、在人耳处减弱13.声音可以传递信息,例如:B超,也可以传递能量,例如:清洗钟表,除去结石。
蝙蝠利用回声来确定目标的方法叫做回声定位,根据回声定位原理,发明了声呐。14.原声和回声的时间间隔大于0.1秒(或者离障碍物距离为17m)才能产生回声。
回声测距离:2s=vt第二章 光现象 基础知识 1. 光源:自身能够发光的物体。太阳是自然光源,电灯、烛焰是人造光源。
月亮和所有的恒星不是光源。2. 光在同种均匀的介质中沿直线传播。
能解释影子的形成和小孔成像。3.真空中的光速是宇宙中最快的速度,用字母c表示:c=3*108 m/s 光在水中的速度约是真空中的3/4在玻璃中光速为真空中2/34.光遇到水面,玻璃以及其他许多物体的表面都会发生反射。
光的反射遵守反射规律。(1)反射光线、入射光线和法线在同一平面内(2)反射光线、入射光线分居法线两侧(3)反射角等于入射角5.在反射现象中,光路可逆。
反射分为镜面反射和漫反射。镜面反射:表面光滑,平行光线入射,反射光线还是平行的。
漫反射:表面粗糙,平行光线入射,反射光线向四面八方。6.光从一种介质斜射入另一种介质时,传播方向发生偏折,这种现象叫光的折射。
发生折射时,同时一定也发生发射。折射现象中光路也是可逆的。
7.光从空气斜射入水或者其它介质中时,折射光线向法线方向偏折。光的折射定律:三线共面,两线分侧,两角不等(空气中角大些)折射现象:钢笔错位、池水变浅、水中叉鱼、海市蜃楼等8.一束白光(太阳光)通过三棱镜分解成为红橙黄绿蓝靛紫七色光的现象叫做光的色散。
说明白光不是单色光,而是各种单色光组成的复合光。彩虹是太阳光被水滴色散而成。
9.光的三原色:红、绿、蓝 颜料三原色:青、黄、品红 透明物体的颜色有通过它的色光决定,不透明物体的颜色由它反射的色光决定。10、红外线位于红光以外,一切物体都在不停地发射红外线,物体温度越高,辐射的红外线就越多,物体辐射红外线同时也在吸收红外线。
红外线作用:①热作用:加热食物 热谱图诊病 ②红外遥感:地球勘测、寻找水源、监视森林火灾等③遥控:电视机、空调等11.紫外线位于紫光以外,太阳光是天然紫外线的重要来源。臭氧可以吸收紫外线,避免过量的紫外线对人体伤害。
紫外线作用:①杀菌:医院的紫外线灯②紫外线的荧光效应:验钞机、防伪③适当的紫外线照射有利于人体合成维生素D,促进身体对钙的吸收,对人体骨骼生长和健康有好处。第三章 透镜及其应用1. 中间厚边缘薄的透镜叫凸透镜,边缘厚中间薄的透镜叫凹透镜。
通过光心的光线不改变传播方向。2. 凸透镜有两个实焦点,焦点到光心距离叫做焦距。
凹透镜有两个虚焦点。3. 凸透镜对光线有会聚作用,凹透镜对光线有发散作用。
4. 三条特殊光线:①过光心的光线不改变传播方向。②平行于主光轴的光线经折射后过焦点,对凹透镜来说,它的焦点是虚焦点,是折射光线的反向延长线过焦点③过焦点的光线经折射后与主光轴平行。
对凹透镜来说是虚焦点,是入射光线的正向延长线过焦点。5. 照相机的镜头是个凸透镜,调焦环的作用是调节镜头到胶片的距离,拍近景时,镜头往前伸,拍远景时,镜头往后缩,光圈控制进入光的多少,快门控制暴光时间。
6.u>2f 倒立 缩小 实 照相机u=2f 倒。
