Spectrophotometers employ various sources of light. Which of the following is NOT true for spectrophotometer light sources? O Dueterium arc lamps use controlled electric discharges to cause D; to dissociate and emit visible radiation. OA silicon carbide globar emits infrared radiation when heated to near 1500 K O Lasers emit radiation of a single wavelength. O Tungsten lamps emit radiation over the visible spectrum and parts of the ultraviolet and infrared spectrums. O Light emitting diodes emit narrow bands of visible and near-infrared radiation.

On the Moon’s surface, lunar astronauts placed a corner reflector, off which a laser beam is periodically reflected. The distance to the Moon is calculated from the round-trip time. What percent correction is needed to account for the delay in time due to the slowing of light in Earth’s atmosphere? Assume the distance to the Moon is precisely 3.84×108 m , and Earth’s atmosphere (which varies in density with altitude) is equivalent to a layer 30.0 km thick with a constant index of refraction n = 1.000293.
Chlorophyll absorbs photons strongly in two bands, one between 340 and 450 nm and the other between 650 and 680 nm. Chlorophyll collects and transfers the photon energy to fix CO2 into carbohydrate CH2O units according to CO2 + H2O → (CH2O) + O2 where the (CH2O) indicates one carbon unit of the carbohydrate. The average enthalpy change for the addition of a carbon unit to a carbohydrate is ΔH = 485 kJ/mol. What is the minimum number of 660 nm photons needed by chlorophyll to add a carbon unit to a carbohydrate? (Remember that there’s no such thing as a partial photon.)
