Question

What function accurately represents the sine curve for red light?

f(x) = sin pi over 640x

f(x) = sin 640_x

f(x) = sin 320_x

f(x) = sin pi over 320x

Answer 1

I can firmly say that is not the answer ^

or im missing something and dont know it yet

Answer 2

The curve is represented by f(x) = sin 320πx
