Question

The graph of the sine curve below is of electromagnetic energy that represents orange light: (Image below)

What function accurately represents the sine curve for orange light?

Answer 1

Options:

Answer 2

A whole period, sin(x), is 2pi, if one period is 610, this means:

610x=2pi
\[x=\frac{2\pi}{610}=\frac{\pi}{305}\]
So,
\[f(x)=\sin(x)-->\sin(\frac{\pi}{305}x)\]
