A.      Triangular method of sketching

B.      Base line method of sketching

C.      Cross projection method of sketching

D.     Compass point method

ANSWER: C

Explanation

Baseline Mapping—

·         A baseline is developed or identified from which to conduct measurements. This can be an existing area, such as the edge of a roadway, a wall, fence, etc., or it can be developed by personnel, such as by placing a string or tape measure through the scene and conducting measurements from there.

·        In the case of the latter, the line should be run between two known fixed points, such as trees or other identifiable points.

·         Once the baseline is established, measurements are taken from the baseline at an approximate 90 degree angle from the baseline to a point on the identified item or area of the crime scene.

·         Typically, most measurements are made either to center mass of the item or to the nearest point of the item to the baseline.

Rectangular Coordinate Mapping—

·         It utilizes two such baselines instead of one. Two measurements are taken to a point on an item or location at the scene. One from each identified baseline.

·         Some personnel choose to measure to two or more points on an item, using multiple rectangular measurements as a way of increasing accuracy, while others simply choose to measure to an arbitrarily-identified center mass of the object in question or point to which the measurements are being taken.

·         This method is especially useful in confined spaces and smaller interior scenes.

Triangulation Mapping—

·         This is the most accurate method.

·         It uses two fixed points. From these two fixed points, measurements are taken to specified points on an item or within the crime scene.

·         There is no need to worry about whether or not measurements have been made at a right angle because the points derive from a known fixed point, such as the corner of a room, or edge of a door frame.

·         From these fixed points, a minimum of two measurements are made to each identified point.

·         If the object is of a fixed or constant shape (e.g., a firearm or item of furniture), then, the object is measured to two points, from the two fixed points, for a total of four measurements.

·         If the object is of variable shape/ size(e.g., puddle of water, pool of blood, or pile of clothes), then the object is measured to an approximate center of mass.

Polar/Grid Coordinate Mapping—

·         It utilizes polar coordinates.

·         It is a two-dimensional system that indicates the location of an object by providing the angle and distance from the fixed or known point.

·         In order to conduct measurements by this method a transit or compass is necessary to measure the angles and polar directions.

·         This method is best utilized in large outdoor scenes with very few landmarks (e.g., a plane crash in the forest or large field).

Q 25.  In microscopy, let 'n' be the refractive index of the medium through which light travels from the object to the lens. If there is increase in 'n', then which of the following statements is true?

A.      It increases the numerical aperture of the objective and decreases the resolving power of the microscope

B.      It increases both the numerical aperture of the objective as well as resolving power of microscope

C.      It decreases the numerical aperture of the microscope as well as resolving power of the microscope

D.     It decreases the numerical aperture of the objective, but increases the resolving power of the microscope

ANSWER: B

Explanation

·     Numerical aperture of a microscope objective is a measure of its ability to gather light and resolve fine specimen detail at a fixed object distance.

·         It is a number that expresses the ability of a lens to resolve fine detail in an object being observed.

 Numerical Aperture (NA) = n(sin µ)

n= refractive index of the medium between the objective front lens and the specimen

µ= one-half angular aperture of the objective.

Liquid material	Refractive index
Water	1.33
Glycerin	1.47
Immersion oil	1.51
