What will happen when a ringing tuning fork is lowered into water?
What will happen when a ringing tuning fork is lowered into water? When struck, the double-pronged metal rod vibrates at a constant frequency — and thus emits a constant pitch. The naked eye can’t spot the vibrations, but dipping the tuning fork in water and slowing down the footage make them anything but invisible. What […]
What is the difference between earthquake and fault?
What is the difference between earthquake and fault? Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to […]
