A) unchanged
B) halved
C) doubled
D) quadrupled
Correct Answer: C
Solution :
Since frequency remains unchanged \[v=v\] \[\frac{v}{\lambda }=\frac{v}{\lambda }\] \[\frac{v}{\lambda }=\frac{2v}{\lambda }\] \[\lambda =\frac{2v}{v}\lambda \] \[\lambda =2\lambda \] Hence, its wavelength will become twice.You need to login to perform this action.
