An 11-mm wide diffraction grating has rulings of 550 lines per mm. Light is incident normally on the grating. The longest wavelength that forms an intensity maximum in the fifth order is closest to? The correct answer is 488nm but I cant seem to get that answer.

Math- steve or ms. sue
does the data in the table represent a direct variation or an inverse variation? x 2 4 8 12 y 4 2 1 2/3 Choices: inverse variation; xy = 8 direct variation; y = 8x inverse variation;y/x = 8 *direct variation; y = 8/x Thank You.

Theres this chemistry problem im getting stuck in because i'm confusing myself with the math. Equation given = %O2 saturation = 100 x (pO2/(pO2 + K) %O2 = 35 K = 1.51 how do I calculate pO2?? I can't seem to cancel them out correctly. Answer = 0.813
