Answer:
[tex]f(x) = sin(\frac{\pi x }{215} )[/tex]
Step-by-step explanation:
We are given the graph of the sin curve that shows the electromagnetic energy which represents indigo light.
According to the graph, we see that the period of the sin curve is 430.
Now, we know that the period of sinx is [tex]2 \pi[/tex] and sinax is [tex]\frac{2 \pi}{a}[/tex].
So, we get that the period of sin430x is [tex]\frac{2 \pi}{430}[/tex] = [tex]\frac{\pi}{215}[/tex].
Hence, the accurate function for the indigo light is [tex]sin(\frac{\pi x}{215})[/tex].
