A) \[\frac{1}{c}(6\widehat{k}+8\widehat{i})\,cos[(6x+8z-10ct)]\]
B) \[\frac{1}{c}(6\widehat{k}-8\widehat{i})\,cos[(6x+8z-10ct)]\]
C) \[\frac{1}{c}(6\widehat{k}+8\widehat{i})\,cos[(6x-8z+10ct)]\]
D) \[\frac{1}{c}(6\widehat{k}-8\widehat{i})\,cos[(6x+8z+10ct)]\]
Correct Answer: B
Solution :
[b] |
Phase angle of E at. |
As E and B oscillate in same phase |
Phase angle of B must be |
Direction of wave propagation |
Let and unit vector in direction of propagation of EM wave is |
