(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two narrow slits are 0.12 mm apart. Light of wavelength 550 nm illuminates the slits, causing an interference pattern on a screen 1.0 m away. Light from each slit travels to the m= 1 maximum on the right side of the central maximum.

Part A -

How much farther did the light from the left slit travel than the light from the right slit?

2. Relevant equations

y_{m}= (m*lambda*L)/d

theta_{m}=lambda/d

r=d*sin(theta)

3. The attempt at a solution

So...

L=1*10^9nm

d=1.2*10^6nm

lambda=550nm

m=1

I have tried a few different things, but I have no idea as to correctly proceed. I have been sticking those numbers into the equations above, but I am not getting any good answers. I must be missing something obvious...
