1) the spectrum of lithium has a red line of 670.8 nanometers. (remember 1 m = 1 x 109 nm) a. convert the nanometer to meter using dimensional analysis. b. calculate the frequency of the wave. c. calculate the energy of a photon with this wavelength.

E = ħc / λ
 ħ = plancks constant = 6.626x10^-34 Js
c = speed of light = 2.999x10^8 m/s
λ = wavelength of light = 670.8x10^-9 m
 
E = (6.626x10^-34 Js) x (2.999x10^8 m/s) x (1 / 670.8x10^-9 m)
E = 2.962x10^-19 J

3x10^8 / (670.8 * 10^-9) =4.47x10^14 Hz
 
4.47x10^14 Hz multiplied by plank's constant = 2.9634x10^-19

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.

C) electrons encircling a nucleus with neutrons and protons
