Question

Which waves are recorded on a seismograph after the P waves?

विकल्प

• Primary waves

• Push waves

• Shear waves

• Surface waves

Answer 1

Shear waves

Explanation:
After the P waves (primary waves), the shear waves (S waves) are recorded on a seismograph. P waves travel fastest and arrive first, while S waves move more slowly and arrive next. They shake the ground perpendicular to their direction of travel and are important for studying earthquakes.
