Flashcards in Lecture 2a optical microscopy Deck (12):
1

define white light

all colours of visible spectrum represented

2

define emission spectrum

the wavelength(s) of light emitted by a light source when electrical nrg is applied

3

define angle of incidence (I)

angle btw incident light ray and normal

4

define angle of reflection

angle at which light rays are bounced back from a surface

5

define angle of refraction

the angle btw refracted light ray and normal

6

define angle of refractive index (RI or n)

ratio of speed of light (c) in vacuum relative to that in a given medium

7

define diffraction

light scatter as it passes by and contacts objects

8

define total internal reflection

j

9

define focal point

point at which refracted rays converge on the other side of the lens

10

define focal length

distance from the midpoint of the lens to the focal point

11

describe relationship btwn angle of incidence and able of reflection of light ray on flat service

wha

12

what happens to light ray when it travels btw diff media with AOI = 0
