c) Optical Resonance
d) Mechanical Resonance​

Answer 1

Answer:

May be the ans will c..............

Answer 2

Option (d) is the correct answer

Barton's pendulum is an example of  Mechanical Resonance

Explanation for correct answer

• Barton's pendulums are examples of demonstration of a resonance effect.

• The experiment of Barton's pendulums demonstrates the physical phenomenon of resonance
• Here the response of pendulums to vibration is at, below, and above their resonant frequencies.
• In the construction, approx 10 different pendulums are hung from one common string.
• It vibrates at the driver pendulum with resonance frequency,
• It causes the target pendulum to swing along with the maximum amplitude.
• The other pendulums to the side do not move as well, thus demonstrating how torquing a pendulum at its
• The resonance frequency is the most efficient with the other pendulums to the side.

Explanation for incorrect answer

Option (a) Acoustic resonance is an incorrect answer because here the pendulum does not move on the sound but moves with mechanical moevement.

Option (b) Electrical resonance is an incorrect answer because here the pendulum does not move on the electrical source but moves with mechanical movement.

Option (c) Optical resonance is an incorrect answer because here the pendulum does not move on the light  but moves with mechanical movement.
