- 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.
