Sodium vapor lamps are used to illuminate streets and highways. the very bright light emitted by these lamps is actually due to two closely spaced emission lines in the visible region of the electromagnetic spectrum. one of these lines has a wavelength of 5.890 x 10⁻⁷ m, and the other line has a wavelength of 5.896 x 10⁻⁷ m. a) what are the wavelengths of these radiations in centimeters? b) calculate the frequencies of these radiations. show work

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
