Hello there.I have a question about how to find the frequency cutoff in a breadboard with oscilloscope,multimeter etc

Ok the circuit it simple.Ac voltage source in series with a resistor,which is in series with a capacitor.I am given that in the frequence cutoff the voltage of the capacitor is let's say T.

So how to find the cutoff frequency?Here is how i think i should find it.

I connect the function generator to the resistor and capacitor.Now i place the multimeter(measuring voltage) across the capacitor.

I change the frequency,until i see that the multimeter got the known voltage(aka T).Then i connect the multimeter across the capacitor again and i measure the frequency.Then i found the frequency cutoff.

Is this the way it should be done?I thought to use the oscilloscope for the cutoff but i don't think i can do it that way.

Thanks in advance for your time and attention
