FRSC 365 EXAM 1 PART 1 QUESTIONS AND VERIFIED ANSWERS
LATEST UPDATE
why microscopes are important
because they are the most utilized in forensics
what is light
light is a wave
Lightwaves
the movement of light, point A to point B
waves have 2 fields
electric and magnetic field
wave motion
sinusoidal fashion
wavelength of light is going to affect the
visible region
Amplitude
Height of a wave
wavelength
The distance between two corresponding parts of a wave
one oscillation
Frequency is the number of oscillations per second
3 things you want microscope to do
, 1. good resolution (see good detail)
2. magnification
3. good contrast
types of light
1. monochromatic
2. polarized
3. coherent
4. collimated
monochromatic light
one color of light
polarized light
light that vibrates in the same plane (parallel to each other)
coherent light
monochromatic light where all the light waves are in sync, appear to be more intense
(bright light source)
Collimated light
refers to the direct of propagation, if all light rays are running parallel to one another and
weren't diverging or converging
common source of light collimated and coherent
laser pointer
4 things that happens when light strikes an object
1. absorption
2. refraction
