Homework Statement:
How big is the extinction in the H-band?
Relevant Equations:
E(B-V) = A_B - A_V
Hey, I'm totally blank on this problem, and I'm not even sure what to solve for.

I'm told that the H band, which is in 1.63 μm, has an extinction law A_H = 0.591 * E(B - V) and I'm supposed to answer how big the extinction is in the H band.

And I'm confused because it involves the difference between the B and V band, and I'm not sure why I should use the wavelength of the H band. I'm tempted to say it is just 0.591
I'd appreiate any input.

Thank you for the links.
No, it doesn't the equation, just states it in the introductory chapter.

So are you able to solve the problem now?
