在双缝干涉实验中,以白光为光源,在屏幕上观察到了彩色干涉条纹.若在双缝中的一缝前放一红色滤光片(只能透过红光),另一缝前放一绿色滤光片(只能透过绿光),这时(A)只有红色和绿色的双缝干涉条纹,其它颜色的双缝干涉条纹消失.(B)红色和绿色的双缝干涉条纹消失,其它颜色的双缝干涉条纹依然存在.(C)任何颜色的双缝干涉条纹都不存在,但屏上仍有光亮.(D)屏上无任何光亮.
In the double-slit interference experiment, white color light was used as a light source, and color interference fringes were observed on the screen. If a red filter (only through red light) is placed in front of a double seam, the other seam is placed in front of A green filter (can only transmit green light). At this moment (A) there are only red and green double-slit interference fringes. The other double-slit interference fringes disappear. (B) Red and green double-slit interference fringes disappear The double-slit interference fringes of other colors still exist. (C) Double-slit interference fringes of any color are not present, but there is still light on the screen. (D) There is no light on the screen.
