Can light gates be used in pairs to start and stop a timer (electronic) . For eg when a bead goes through the first light gate it starts the timer and when it goes through the second light gate it stops the timer ?

You could do that for sure. If this is with reference to a question regarding light gates, I'd think it faulty to say that you'd lose marks provided you state a coherent explanation of how you'd use the gates. It could be convoluted, but so long as you explain it, it's fine. Needless to say, yes is the answer you're looking for.
