3. PREFACE
The flux of light received in a unit area of a ceriain
side being
shone
is
popularly
known as illumination.
ln both United Kingdom and
America its
unit
is
known
as
footcandles light, but in Europe it is
known
as
meter candlelight.
One foot-candles
light is the illumination
of
light that
falls on one side that lies in a distance one foot
away from a one footcandlelight and exactly
iniersecting the light. lts
abbreviated
form is written
as
1 Fc=1 Lm/ft,
similarly, one-meter candlelight
is
the illumination
of
light that falls
on a side
that lies in
a distance one meter away from a one meter
candlelight and exactly
intersects the light. lt is
also
called
Lux i,e. the flux
of
light
being
received in
each sq. meter is called the illumination of one
lumen.
