molecular cloud (around 100 K) molecular oxygen emission is strongest as a wavelength is 0.2521 cm. Determine the speed ( in km/s ) of a low temperature molecular cloud containing molecular oxygen if its strongest emission is at wavelength of 0.1855cm. This cloud is moving toward us so your answer should be negative.
