Show all of your working together with the final result. 2) The sampling interval for a seismic survey is 5 ms. what is the Nyquist frequency (show all of your working). In the context of this seismic data, what does this mean in simple terms? 3) For the geological model below calculate the reflection coefficient at each interface and the RMS velocity at the base of each layer. Show all your working. Layer 1: density = 1231 kg/m3, v = 1701 m/s, travel time = 2.24 s Layer 2: density = 1901 kg/m3, v = 2013 m/s, travel time = 1.15 s Layer 3: density = 2256 kg/m3, v = 2378 m/s, travel time = 1.07 s Timeline for submission: Oct 6 2014 2:38PM EST Pages required 2 (550 words) – Times New Roman – Double spaced Paper should follow MLA citation with 2 references
