Calculation of true thickness of the bed

Q) If quality factor of the weathered sedimentary rock is 30, wavelength of the seismic wave is 200m and velocity of the wave is 2000m/s then calculate the Inverse absorption coefficient.

    Solution: 

(Thanks to Rajkumar, AKNU)

    Given values                                                       

    Quality factor (Q) = 30

    Wavelength ($\lambda$) =200m

    Velocity V =2000 m/s

Absorption coefficient $\alpha=\frac{\pi}{Q \lambda}$

Inverse of the absorption coefficient

$\alpha^{-1}(or)D=\frac{Q\lambda}{\pi}$

 

$D=\frac{30\times200}{3.14}$ = 1910.82m
