Three discrete spectral lines occur at angles of 10.3°, 13.9°, and 15.0° in the first-order spectrum of a grating spectrometer. (assume that the light is incident normally on the gratings.) (a) if the grating has 3 640 slits/cm, what are the wavelengths of the light? (enter your answers from smallest to largest.) (b) at what angles are these lines found in the second-order spectrum? (enter your answers from smallest to largest.)

they should be similar or the same

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
