Light wave is travelling along `y`-direction. If the corresponding `vecE` vector at any time is along the`x`-axis, the direction of `vecB` vector at that time is along

A

y- axis

B

x-axis

C

`+ z axis`

D

`- z axis`

Text Solution

Verified by Experts

The correct Answer is:
D
Propagation direction = `vecE xx vec B`
`implies (hatj)= (hati) xx (-hatk)`
