I didn't find my lab in any website. if possible, please give the steps of the question1,2,4. Question3 has a problem with data, just need a thought

GEOL 2060 Introductory Geophysics: Lab 1 Sept. 18, 2017; due Sept. 25 1. Period, frequency, and wavelength The focus on this lab is on geophysical signals as represented in time and space. These signals are ofien periodic - that is, they repeat in time or space wih a particular period or wavelengtih 10 At 6 sec A: 10V -6 8 10 1S 10 10 1S 20 Time ) Figu1: A simple siusidal signal The plot above is a sinusoidal periodic signal which varies in time (the x axis). In this example, the signal has an omptinta e of 10 V (because 11 ranges from-10 V to +10V , and a period (T) or 10 s (the urne be- tween repetitions of the signal. From the period, we can calculate the repency: the number of repel!tions per unit lime. In this case,,f = 1 /T= 0. I s. A similar calculation relates the zemelength of a spatial signal to its spatial frequency k. For a wave, which varies in both space and time, the period and wavelength are re- lated by the uve velocily c: A-cT. (a) The periods of several signals are listed below. List the corresponding frequency. Use ap- propriate SI units (Hz, mHz, kHz, etc.) such ha he umerical value is belween 0. and 100; use 4 signif- icant digits.

Explanation / Answer

Answer,

1 a) 1 Millisecond is equal to 1 000 Hertz

So 120 miliseconds = 120000 Hz, 12 KHz, 0.0012 Mhz

b) Convert year into seconds

= 1.734 x 10^8 seconds

So it is equal to 1.734 x 10^11 Hz, 1.734 X 10 ^5 KHz and 1.734 x 10^8 MHz

c) 1 pico second = 1 x 10^-12 seconds

= 1 x 10^-9 Hz, 1 X 10^-15 mHz, 1 X 10^-6 Khz

2. 1 cycle per second = 29979245.8 m

a) 320 cycle = 9.59 x 10^9 m

b) 0.02 Cycle = 599584.916 m

c) 4.3 x 10 ^ 6 cycle = 1.289 x 10^ 14 m
