A double beam oscilloscope displays 2 sine waveforms A and B. The time/cm switch is on 150µs/cm and the volt/cm switch on 5 V/cm. The width of each complete cycle is 8 cm for both the waveforms. The height of waveforms A and B are 5 cm and 4 cm respectively. Determine their a) frequency, b) phase difference, and c) peak and d) r.m.s value of voltages. The difference between the two waveforms is 0.7 cm.
