Question
what is the relation b/w E1 &E2 whose respective wavelength r 400& 800 Ao . SIR I WANT TO KNOW THE RELATn b/w ENERGY & WAVELENGTH . ARE THEY DIRECTLY PROPTIONAL ? ANS OF THIS QUES IS E1=2E2
Joshi sir comment
E = hc/λ
so E is inversely proportional to λ
Read 1 Solution.
We know that E=hc/λ where h =planck's constant ,c =speed of light and λ = wavelength. SO
E1=h*c/400
hence h*c =400E1 , equation 1
E2=h*c/800
therefore h*c=800E2 ,equation 2
from eqn 1 and eqn2 ,we get
800E2 =400E1
2E2 =E1
