Answer:
λ=2167.6 nm
The wavelength of light emitted is 2167.6 nm.
Explanation:
We recall that Eₙ=
since there was transition from n7 to n=4 we will first calculate the change in the energy i.e ΔE
ΔE=E₄-E₇
ΔE=
ΔE=-9.1760*10^-20 J
Now:
|ΔE|=Energy of photon=h*v=h*c/λ
λ=h*c/|ΔE|
λ=
λ=2.1676*10^-6 m
λ=2167.6*10^-9 m
λ=2167.6 nm
The wavelength of light emitted is 2167.6 nm.
Answer:
The answer is
<h2>26.94 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 970 g
volume = 36 mL
The density of the object is
We have the final answer as
<h3>26.94 g/mL</h3>
