Forensic Quiz

Question 1

It serves as a central reference point for the intricate interplay of light contributing to the functionality and effectiveness of the lens.

Answer 1

Filter

Question 2

This phenomenon manifests as a distortion in the configuration of the field, causing the edges to either curve inward or outward, adopting the form of a linear trajectory.

Answer 2

Distortion

Question 3

This optical phenomenon stems from the wavelength- dependent refractive properties of the lens material, causing different colors to exhibit distinct focal points.

Answer 3

Chromatic aberration

Question 4

This combination of silver halide crystals and sensitivity specks from the foundation for the light sensitive emulsion commonly found in photographic films and papers enabling the creation of enduring image through the chemical transformation include by exposure to light

Answer 4

Emulsion layer

Question 5

It is sensitive to all colors except red meaning that it records all color except red

Answer 5

Orthochromatic film

Question 6

A filters employed to diminish or control reflections in optical system effectively minimizing unwanted clear or spectral highligh

Answer 6

Polarizing filter

Question 7

This occurs because light hitting the outer parts of the lens is bent more sharply and comes to a focus sooner than the passing through the middle

Answer 7

Spherical aberration

Answer 14

Short focal lens

Question 15

The occurrence of lens defects seems from subtle irregularities present in lenses and minors as well as the divergent reflection or refraction experienced by different segment of the light spectrum

Answer 15
