Answer: choice A) sine of pi/290 times x

=====================================

Work Shown:

T = Period = 580 nm

A = amplitude = 1 = vertical distance from midline to peak

B = 2pi/T = 2pi/580 = pi/290

C = phase shift = 0

D = horizontal midline = 0

..........

y = A*sin(B(x-C))+D

y = 1*sin((pi/290)(x-0))+0

y = sin((pi/290)x)

which matches with choice A
