    You have to find the path difference to X SX = square root of 32 and 52=5 SPX=3+4=7, so path difference is 7-5=2 Wavelength = 0.80m Path diff=n x lambda 2/ 0.80 = 2.5. 2.5 lambda is a destructive interference so a minimum is detected.

    if the voltmeter reading is 4V, then use the formula Vout=V(Total) x RAB/RT 4 is Vout. V total is 9.0 and put your RAB as unknown, RT which consists of RAB and 1.2kohm Then the total resistance, will be 960 ohm hehehe understand?
