FRSC 365 TEST 1 EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
In the visible light spectrum, _____________ will determine the color,
___________ will determine the intensity of color
wavelength, amplitude
3 tasks of a microscope
magnification, resolution, contrast
4 types of light
monochromatic, polarized, coherent, collimated
monochromatic light
light having a single wavelength or frequency
polarized light
light that vibrates in only one direction
coherent light
monochromatic light where waves are in synch
Collimated light
rays of light are running parallel to each other
4 ways light can interact with an object
absorption, reflection, refraction, diffraction
refraction
bending of light either towards or away from the "normal"
, what is the "normal"
perpendicular in between the 2 refractive medium
what determines which way light will refract when it passes through one medium
to another
refractive index (RI)
If light is going from low to high RI, light will bend ___________ the normal
toward
If light is going from high to low RI, light will bend _________ the normal
away from
Diffraction
how light bends/spreads out around a barrier
what is the result of interference between scattered and non scattered light
sample brightness
real image
An upside-down image formed where rays of light meet, opposite side of lens
virtual image
an upright image formed where rays of light appear to meet or come from, on the same
side as the lens
focal point
where all collimated light converges
Ray Trace
a method to determine where image will form based on focal point
lens equation (determining distance the image forms from the lens
