Answer:
screw and pulley
Explanation:
because they didn't have any of the other tools in that time
The assume that goes with the inquiry demonstrates the wavelenghts of the photons transmitted by Balmer arrangement change , from vitality levels (n) 3, 4, 5, and 6 to the vitality level (n) 2, in hydrogen particles.
These are the values shown in the figure
Transition wavelength of the photon emitted
nm
from n=3 to n=2 656<------ this is the value requested
from n=4 to n=2 486
from n=5 to n=2 434
from n=6 to n=2 410
The wavelength of a photon discharged from the n = 3 shell in hydrogen is the primary information of the table, i.e 656 nm.
Using the conversion factor from nm to m that results is :
656 nm * 1 m / (10^9 nm) = 656 * 10 ^ -9 m.
Hope this helps
