Question

The wavelength of photons emitted in the hydrogen spectrum?

Answer 1

Answer:

3669 Armstrong

Explanation:

Balmer series means wavelength is  given by    

λ

1

​  

=R(  

4

1

​  

−  

n  

2

 

1

​  

)

for maximum wavelength the n should be max  so putting n→∞

we get λ=  

R

4

​  

 

putting the Rydberg's constant as R=1.09×10  

7

/m

we get  λ=3669×10  

−10

meter= 3669 Angstrom
