Question

If E→$$=60$$ $$sin$$(8$$ x $$1010$$ $$t-ky)k^$$ represents the electric field associated with an electromagnetic wave in vacuum, then its magnetic field component can be represented by $$(Here$$ E, t and y are in $$V/m$$, second and meter $$respectively).

$$EmBm=c$$⇒$$Bm=603$$ x $$108T=20$$ x $$10-8$$ TDirection of propagation is determined by the direction of E→ x B→.The wave is propagating along $$y-axis$$. Since,  $$k^$$ x $$i^=j^$$,  B→ must be along $$x-axis$$.Also E→ and B→ are always in the same phase.
