Közvetlenül a fényelem előtt kis távolságban, hogy éppen ne érintse elsuhan egy L nyugalmi hosszúságú vékony lemez, amely nyugalmi helyzetben éppen eltakarná a fényelemet.
Legyen a lemez sebessége 0.866*c.
.
Mit mutat a fényelem áramának regisztrátuma? Lesz benne olyan, amikor az árama nullára csökken, vagy csak a felére csökken amikor elhalad előtte a lemez?
.
Hogyan lehet a regisztrátumot kimagyarázni a lemezhez rögzített vonatkoztatási rendszerből?
.
.
(Hagyjuk figyelmen kívül a vezetékhosszakat, a töltéshordozók futási idejét stb.)
