Question Answer
how did newton's corpuscular theory of light explain refectionwhen a light reflects off a plane mirror, the corpuscles bounce off the mirror without loss of speed; their component of velocity parallel to the mirror is unchanged, but the component normal is reversed
how did newton explain refractionwhen light travel through a transparent substance, their velocity parallel to the boundary of the substance is unchanged, but it's normal velocity component increases due the the gravitational force exerted on it's mass by the substance so it's attracted into the substance and so travels faster in the substance

Question Answer
AAAAAA 2 limitaions on detail in TEM imagesample thickness ( electrons passing through lose speed and so de broglie wavelength increased and resolution reduced)
describe STMscanning tunneling microscope; a fine tipped metal probe is placed 1nm above a surface and moved parallel to the surface; the tip is given a -1PD relative to the surface to ensure only one way tunnelling; there is a finite probability that eleectrons will tunnel across to the surface and cause a current; the smaller the gap the larger the current; either constant height or constant current mode could be used
