Ques. 1AIPMT 2002
The velocity of electromagnetic wave is parallel to
- B E
- E B
- E
- B
Answer
(2) E B
Solution
As per NCERT, in an electromagnetic wave E and B are perpendicular to each other and to the direction of propagation.
E.g. E along x, B along y wave travels along +z, i.e. along i j = k
The velocity is parallel to E B
Answer: (2)
