1.A particularly sharp diffraction grating has 12300 lines per
centimeter. A helium light source shines on the grating; a strong
line in helium's spectrum has a wavelength of 447.1 nm. What is the
angular position (in degrees) of this line when it is dispersed by
the diffraction grating?
2.The force repelling two like charges that are 24.6 cm apart is
4.6 N. In units of microCoulombs, what is the magnitude of the two
like charges?
