If a photon dropping from the n = 7 to the n = 1 level hit the surface of Ag, what would be the wavelength of the ejected electron in inches?

366 inches

Explanation:

From;

1/λ = RH(1/nf^2 - 1/ni^2)

Given that;

nf= 1, ni= 7, RH= Rydberg constant for hydrogen

1/λ = 1.097 × 10^7(1/1^2 - 1/7^2)

1/λ = 1.097 × 10^7(1 - 0.02)

λ = 9.3 × 10^-8 m or 366 inches

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

i dont know the answe
