Question

The nature of the size of the shadow depends on *

1 point

Size of the source of light

Size of the object

Distance between source of light and object

All of the above



​

Answer 1

$the \: size \: of \: the \: shadow \: depends \: on \: \\ the \: size \: of \: the \: object \: the \: distance \\ from \: the \: light \: to \: the \: object \: \: and \\ the \: distance \: from \: the \: light \: to \: screen.$

$the \: mie \: algorithm \: assumes \: that \: the \: \\ incident \: light \: is \: in \: the \: form \: of \: a \: plan \\ wave(e.g. \: from \: a \: point \: source \: of \: light \: at \: infinite \: distance)$

$effect \: of \: size \: of \: light \: source \: \\ red = \: point \: source \\ black = diameter \: source \: (sun) \: \\ \gamma = 150 um \\ \alpha = 0.65um \\ perpendicular \: polarisation \\ \:( you \: can \: see \: the \: fig.1) \: at \: the \: top \: of \: answer \:$
