Answer:b) atoms
Explanation:which are in turn made up of protons, neutrons and electrons
Answer:
a region in which particles with an electric charge will experience a force
Explanation:
let me know if its wrong . sorry if it is
Hydrogen's light spectrum is limited to its quanta, so electrons *and photons*, can only travel between the electron orbitals. The light emmited from the sun is almost all the spectrum of light from UV to gamma rays, including the visible spectrum. Thats why there are more lines.
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
A - the amount of time needed to travel the distance
The formula for speed is distance/time and the unit is m/s. Therefore you divide the distance travelled by the time it took to travel it.
