Consider the following statements about S(Secondary) waves:

1. S-waves are slower than P-waves.
2. The direction of vibrations of S-waves is perpendicular to the wave direction.
3. Travel only in Solid medium.

Which of the following statement(s) is/are correct?

• A. 2 and 3 only
• B. 1, 2 and 3 only
• C. 1 and 3 only
• D. 1 and 2 only

Answer 1

The correct option is B 1, 2 and 3 only

-S-waves are slower than P-waves (4 to 6 Km/s).
-The direction of vibrations of S-waves is perpendicular to the wave direction(TRANSVERSE WAVES).
-Travel only in Solid medium.Thus can’t travel in outer Core which is Molten state.
