*Aufgabenstellung:*
|
||||
|
||||
In einem Meeresgebiet nimmt die Lichtintensität unter Wasser mit zunehmender Wassertiefe annähernd exponentiell ab.
|
||||
Während sie an der Wassoberfläche $100%$ beträgt, liegt sie in 1.80m Tiefe bei nur noch etwa $75%$
|
||||
|
||||
_a)_\
|
||||
Beschreiben sie die Lichtintensität in Abhängigkeit von der Wassertiefe (in m) durch eine Exponentialfunktion und skizzieren Sie den Graphen der Funktion im Intervall $[0;10]$.
|
||||
|
||||
_Es soll jetzt geklärt werden wie man zur folgenden Formel kommt:_
|
||||
|
||||
|
||||
$
|
||||
f(x)&=#pin(3)1#pin(4) dot #pin(1)0.75 #pin(2) ^(x / 1.8)=(0.75^(1 / 1.8))^x=0.8523^x
|
||||
$
|
||||
|
||||
#pinit-highlight-equation-from(
|
||||
(1, 2),
|
||||
(1, 2),
|
||||
height: 2.5em,
|
||||
[
|
||||
$75%$ Lichtintensität
|
||||
],
|
||||
)
|
||||
#pinit-highlight-equation-from(
|
||||
(3, 4),
|
||||
(3, 4),
|
||||
height: 4.5em,
|
||||
fill: blue,
|
||||
[
|
||||
$100%$ Lichtintensität
|
||||
],
|
||||
)
|
||||
|
||||
|
||||
$1$ → 100% Lichtintensität\
|
||||
$0.75$ → 75% Lichtintensität\
|
||||
$1.8$ → 1,80m Tiefe
|
||||
|
||||
*Lösung:*
|
||||
|
||||
$
|
||||
f(x)&=1 dot 0.75^(x / 1.8)=(0.75^(1 / 1.8))^x=0.8523^x
