Consider the following statements with reference to Secondary waves (S-Waves) generated during an earthquake: 1. They create troughs and crests in the material through which they pass. 2. The direction of vibrations of S-waves is perpendicular to the wave direction in the vertical plane. Which of the statements given above is/are correct?
Both 1 and 2
Explanation: S-waves, or secondary waves, are shear waves that move perpendicular to the direction of propagation. They create troughs and crests in solids and are transverse in nature. Both statements are scientifically accurate. ---
