8 In a stereo pair, which of the following statements is true (multiple choice questions) A. The larger the horizontal parallax, the closer the distance B. The higher the degree of refraction, the less the total number of images required C. The overlap is between 0 and 1 D. Transverse parallax can be used to measure the depth of field

In trying to minimise errors that come with using a tape in linear measurements, Mapalo suggested to the class that an EDM be used to compute the distance from BM1 to point A. A distance of 2122.241m was measured. Given that a frequency of 1.4985MHz was used, speed of light c = 299792458m/s,  the refraction index of 1.0003 and that the effective wavelength measures to a centimetre,  determine the phase measurement (i.e. Phase Distance and the corresponding Phase angle)

definition of a datum in seismic reflection Choose one: a. a level equal to the mean-sea level b. all of the options are true c. a level were time is zero d. datum is the surface level of the earth
