प्रश्न
What conclusion can be obtained from the observation that when the prongs of a sound making tuning fork touch the surface of water in a beaker, the water gets splashed?

The conclusion from the observation is that the prongs of the tuning fork are vibrating in simple harmonic motion and transmitting energy to the surrounding medium. The prongs move backward and forward continuously to produce compression and rarefaction, which is observed by the splash of water.
