Answer:
[tex]p(n)=5(0.99)^{n}[/tex]
Step-by-step explanation:
We can use the form of [tex]p(n) =ab^{n}[/tex] to base our answer on.
We know that a, the starting output is 5 mW
And we know that the laser beam loses 1% of its power every time it reflects.
We need to find what the power is after it loses 1%, so we can do some simple math
[tex]1-0.01=0.99[/tex]
that would mean that b = 0.99
Now that we know a and b, we can set up the equation by plugging in the values we now know
[tex]p(n)=5(0.99)^{n}[/tex]
