Exercise 6b: Frequency & Wavelength SLIDE 20 For Exercise 6b, we will use this seismic section There are blow-ups of 2 windows We want you to calculate the frequency and wavelength of the seimic in each window The relevant equations are in the upper right We get the apparent (observed) frequency for each window by counting the number of cycles (1 cycle = a black followed by a white) over a certain time interval (e.g., how many black-white couplets occur over 0.1 seconds) We have an empirical formula to get the dominant frequency given the apparent frequency Once we have the dominant frequency, we can calculate the wavelength () using the third equation Give the students a little introduction to the exercise, and then some time to calculate Courtesy of ExxonMobil L 6 – Seismic Reflections
