Question

what voltage must be applied to an x ray tube for it to emot x ray with a minimum wavelength of 30 picometwr and also find the corresponding maximum frequency as well
​

Answer 1

Answer:

Explanation:

Wavelength of X-ray, λ=0.4125A=0.4125×10  

−10

m

For minimum wavelength we know that:  

eV=  

λ

hc

​  

 

∴V=  

eλ

hc

​  

 

=  

1.6×10  

−19

×0.4125×10  

−10

 

6.6×10  

−34

×3×10  

8

 

​  

 

=3×10  

4

V=30kV

srry dont know max

hope it helps
