FRSC 365 TEST 1 EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS
Refractive Index
How the speed of light changes in a medium as compared to the speed of light in a
vacuum
Four actions of light
Refract, absorb, diffract, and reflect
Snell's Law
n1sin(theta1)=n2sin(theta2)
Airy disc formula
d=0.61 * wavelength/NA
Four abberations
Chromatic, distortion, spherical, and curvature of field
Corrections for aberrations
Plano, Achromat, Semi-apochromat, and apochromat
Advantages of the stereomicroscope
Good depth of field, wide field of view, good working distance, allows you to see in 3D
Types of stereomicroscopes and their defects/advantages
Greenough: Cheaper, smaller, Keystone Effect
CMO: Complex, space for accessories, Perspective Distortion
Numbers on eyepieces and field of view equation
