1. Typical Vertical Resolution
Shallow Event
Velocity = 2000 Meters / sec
Pulse:
Center Frequency = 50 Hz
Period = 1 / 50 = sec
Wavelength = .020 x 2000 = 40 Meters
Limit of resolution = 40 /4 = 10 Meters
Deep Event
Velocity = Meters / sec
Pulse:
Center Frequency = 20 Hz
Period = 1 / 20 = sec
Wavelength = x = 150 Meters
Limit of resolution = 150 / 4 = Meters
SLIDE 11
ANSWER
The shallow zone of interest has a wavelength of 40 meters; a vertical resolution of 10 meters
The deep zone of interest has a wavelength of 150 meters; a vertical resolution of 37 meters
