A) \[\cos kx\] is maximum
B) \[\cos kx\] is minimum
C) sin \[\omega t\] is maximum
D) sin \[\omega t\] is minimum
Correct Answer: A
Solution :
Intensity \[\propto {{(Amplitude)}^{2}}\]\[\propto {{(2a\,cos\,kx)}^{2}}\] Hence, intensity will be maximum when \[\cos \,kx\] is maximum.You need to login to perform this action.
