4.如图所示,一束复色光经平行板玻璃砖折射后形成两束单色光a、b。a光与b光相比较,下列说法中正确的是A.在空气中a光更容易发生明显的衍射B.在玻璃砖中a光的波长更长…iC.在玻璃砖中a光的传播速度更犬D.在空气中a光光子的动量更大
16.(14分)如图所示,在平面直角坐标系xOy的x轴下方存在方向竖直向上、电场强度大小E2=4N/CC的匀强电场,x轴上方存在方向水平向右、电场强度大小E=4N/C的匀强电场,等边三角形abc边长L=1m,底边bc在x轴上。比荷qm=110^10C/kg-1×10C/kg的带正电粒子在ν轴上的P(0,-0.75m)点以v1=0.510^5m/s的速度沿y轴正方向射出,经O点进入电场,粒子恰好经过等边三角形ab边的中点d(图中未标出),不计粒子的重力。(1)求粒子经过O点时的速度大小及d点的坐标;(2)若使粒子经过a点,求粒子从P点射出时的速度大小。
