A) \[1:2:3\]
B) \[1:\frac{1}{3}:\frac{1}{5}\]
C) \[1:3:5\]
D) \[5:3:1\]
Correct Answer: B
Solution :
As \[l=\frac{{{\lambda }_{1}}}{4}\] \[{{\lambda }_{1}}=4l\] \[l=\frac{3{{\lambda }_{2}}}{4}\] \[{{\lambda }_{2}}=\frac{4l}{3}\] \[l=\frac{5{{\lambda }_{2}}}{4}\] \[{{\lambda }_{3}}=\frac{4l}{5}\] \[={{\lambda }_{1}}:{{\lambda }_{2}}:{{\lambda }_{3}}=1:\frac{1}{3}:\frac{1}{5}\]You need to login to perform this action.
