25) A seismic reflection survey is carried out using a 10 milli seconds wavelet over a subsurface medium having an average P-wave velocity of 1600 m/sec. The best resolution which is obtained on the basis of Rayleigh criteria is _______m
(Thanks to Chandrasekhar, ANU)
Solution:
Given that time (t) = 10 milli seconds=0.01 seconds
Velocity (V_ {p} ) = 1600 m/s
The Best resolution (\frac{\lambda}{4})= ?
We know that c= f\lambda
\lambda= \frac{c}{f}
\lambda=ct
\lambda=(1600)(0.01)
\lambda=16
The best resolution is given by=\frac{\lambda}{4}
=\frac{16}{4}
