2. Sodium and mercury vapor lamps are commonly used as their efficiency is much higher than the normal LEDs. They can light up a large area and hence these are used in public places.
These are generally the primitive lamps used for lighting. But due to their high efficiency and lighting intensity they are still in use at some places.
3. Absorption spectrum measures the absorption of radiation as a function of wavelength of absorbed radiation while emission spectrum measures the emission of absorbed radiation by a sample as a function of wavelength.
When a certain compound is irradiated by radiation of certain wavelength, the absorbed radiation of the sample is taken in absorption spectrum. After the absorption, the compound starts emitting electromagnetic radiation, this emitted radiation is usually taken in emission spectrum.

W8. (a) Calculate the angular separations of the two Sodium lines given in Reference Table 19.1, using individual wavelengths and Eq. (19.1) for the first-order spectrum; i.e. in the first-order case (m-1 in Eq. 19.1), you calculate θ' (in degrees) for λ, of Sodium (589.0 nm) and then for λ compute q, (589.6 nm, m-1). The angular separation is (expressed in degrees). (b) Repeat the calculations for the second-order case (m 2 in Eq. 19.1), where the angular separation is...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
