D
सीस्मोमीटर - पृष्ठतल की वक्रता
Seismometer - Curvature of surface
Correct
Official Solution & Explanation:
Correct Answer: Option D(सीस्मोमीटर - पृष्ठतल की वक्रता)
सीस्मोमीटर (Seismometer) भूकंपीय तरंगों की तीव्रता मापने वाला यंत्र है, न कि पृष्ठतल की वक्रता नापने वाला। पृष्ठतल की वक्रता स्फेरोमीटर (Spherometer) द्वारा मापी जाती है।
A seismometer measures seismic waves caused by earthquakes, not the curvature of a surface (curvature is measured by a spherometer).
