A)
B)
C)
D) All of these
Correct Answer: D
Solution :
[d] Longest wavelength is specified by \[\lambda =2L.\]next by \[\lambda =L.\] Then \[\lambda =L\times \frac{2}{3}.\]etc. In general \[{{\lambda }_{n}}=\frac{2L}{n},n=1,2,3...\] For (1) \[\lambda =\frac{2L}{3}\] For (2) \[\lambda =L\] For (3) \[\lambda =2L.\] Hence, all are possible.You need to login to perform this action.
