Theo bài ta có : \(2\left(N-1\right)=4798\rightarrow N=2400\left(nu\right)\)
\(\rightarrow L=3,4.\dfrac{N}{2}=4080\left(\overset{o}{A}\right)\)
\(\rightarrow L=0,4080\)\(\left(\text{µm}\right)\)
\(\rightarrow\left\{{}\begin{matrix}2A+3G=3120\\2A+2G=2400\end{matrix}\right.\rightarrow\left\{{}\begin{matrix}A=T=480\left(nu\right)\\G=X=720\left(nu\right)\end{matrix}\right.\)
