22．如左圖所示，兩根足夠長的光滑直金屬導(dǎo)軌MN、PQ平行放置在傾角為θ的絕緣斜面上，兩導(dǎo)軌間距為L。M、P兩點間接有阻值為尺的電阻。一根質(zhì)量為m的均勻直金屬桿ab放在兩導(dǎo)軌上，并與導(dǎo)軌垂直。整套裝置處于磁感應(yīng)強(qiáng)度為B的勻強(qiáng)磁場中，磁場方向垂直斜面向下。導(dǎo)軌和金屬桿的電阻可忽略。用與導(dǎo)軌平行且向上的恒定拉力F作用在金屬桿上，金屬桿ab沿導(dǎo)軌向上運(yùn)動，最終將做勻速運(yùn)動。當(dāng)改變拉力F的大小時，相對應(yīng)的勻速運(yùn)動速度v也會改變，y和F的關(guān)系如右圖所示。

　(1)金屬桿ab在勻速運(yùn)動之前做作什么運(yùn)動?

　(2)運(yùn)動過程中金屬桿ab受到的安培力的表達(dá)式?

(3)若，取重力加速度，試求磁感應(yīng)強(qiáng)度B的大小及θ角的正弦值sinθ

21．如圖所示，玻璃棱鏡ABD可以看成是由ACD、ABC兩個直角三棱鏡組成，一束頻率Hz的單色細(xì)光束從AD面入射，在棱鏡中的折射光線如圖中ab所示，ab與AD面的夾角。已知光在真空中的速度，玻璃的折射率，求：

(1)這束入射光線的入射角多大?(結(jié)果可用三角函數(shù)表示)

(2)光在棱鏡中的波長是多大?

(3)請通過計算說明該束光線第一次入射到AB面上能否發(fā)生全反射?

(1)該簡諧橫波的波長多大?

(2)該簡諧橫波的周期多大

(3)該簡諧橫波的波速v的大小與方向?
