4. To illustrate how apparent resistivity is calculated from an MT time series, look at the time series in the plot below. Vy By PLAN VIEW 5 minutes (a) Vy is the voltage in the y-direction. Estimate the peak-to-peak value. This voltage is measured with a 500 m dipole. What is the value of the electric field strength, Ey? (b) Convert Ey to field units. These are millivolts per kilometre. (c) Measure the peak-to-peak value of the magnetic field, B, in nT. The field unit for magnetic field measurements is nT

Solution

One complete cycle of the wave is related to Associate in Nursing \"angular\" displacement of
2 radians. omega

The part is that the angle of an indication portion, it\'s laid out in angular degrees and
provides a relevance the reference worth of the whole signal. For periodic signals is that the
total point in time of 360 degrees and a amount up to the amount length.
A typical question: what\'s the frequency and also the point in time of a curving waveform?
Does \"one\" signal will extremely have a phase?
Two \"in-phase\" waves have a part (angle) of = zero degrees.
If the frequency = zero cycles/second, then there\'s no AC voltage - that is simply DC. Then there\'ll be no
phase angle gift.

Phase angle (deg) Phase-Laufzeit
(Time shift) Time distinction Laufzeit-Phase
Frequency Frequenz-Phase

= c / f and c = 343 m/s at 20°C.

Calculation between point in radians (rad), the time shift or time delay t,
and the frequency f is:

Phase angle (rad) Bogen-Laufzeit
\"Bogen\" means that \"radians\". (Time shift) Time distinction Laufzeit-Bogenwinkel
Frequency Frequenz-Bogenwinkel

Time = path length / speed of sound
