How does a series capacitor affect a square-wave on-off signal?

I thought C4 would only accumulates positive current from IC7''s pin 3 and release it to IC6''s pin 4. I thought the capacitor should be hold fixed to connect one pin to positive, and another to negative. From what i can see the IC7''s pin 3 is switching from positive current and then to ground on one of the pin of C4. Thank you

Does a charging capacitor emit an electromagnetic wave?

You can generate electric field and (eventually) light with capacitor. But required frequency for visible light is extremely high - c/650nm = 461Thz, way out of reach of current electronics.
