Today the flashing light of Marblehead Lighthouse can be modeled by g ( x ) = sin(π/3) x . How many whole seconds are there between each flash? Enter only the number.

( Hint : Recall that the period of a sinusoidal function is 2π/ b .)

for yours, comparing y = sin(bx) to y = sin(π/3) x
what is the value of b ?

Now put that in your 2π/b
and go for it.
