Is it possible that when my microwave is turned on, the wifi signal becomes weaker?

If you have a wifi network on the 2.4 GHz band, then yes.

Microwave ovens also work on 2.4 GHz, so they could interfere with wifi. Microwave ovens are shielded to prevent the radiation from leaking out, but if the shielding is in somehow deteriorated, there may be some leakage. A typical microwave oven that's active can emit 10,000 times more microwave radiation than a wifi router, so even a small amount of leakage can interfere with signals.
