Helium atoms emit light at several wavelengths. light from a helium lamp illuminates a diffraction grating and is observed on a screen 50.00 cm behind the grating. the emission at wavelength 501.5 nm creates a first-order bright fringe 21.90cm from the central maximum. what is the wavelength of the bright fringe that is 31.60cm from the central maximum?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
