A256-hertz vibrating tuning fork is brought near
a nonvibrating 256-hertz tuning fork. the second
tuning fork begins to vibrate. which
phenomenon causes the nonvibrating tuning fork
to begin to vibrate?
(1) resistance (3) refraction
(2) resonance (4) reflection

(2) Resonance

Explanation:

When an object start vibrating with natural frequency which is also same as the external frequency which is produced then at this position the energy of source and the receiver becomes maximum and this is known as Resonance.

When resonance occurs in the system then system achieve its maximum stability and maximum energy state.

Here we know that a 256 Hz tuning fork is brought near other tuning fork of same frequency so since the frequency is same here so they both will achieve the condition of maximum energy.

So it is known as Resonance
