A question of frequency

In episode 61 of the Sky High column, Meghnath explains the concept of frequency and communicating through resonance and oscillations

Story so far: While telling Ravana’s sons how Ravana and Kubera had a difference of opinion about using the Pushpaka Vimana, Prahasta brings up Brain-Computer Interface and its application in the 21st century.

Atikaya: So, I can kind of visualise how it works but how did Vishwakarma decode it and make it work in our Tretayuga? And how is Neuralink, which lies in the future, connected to the Pushpaka Vimana?

Prahasta: In the 21st century, the technology used by Elon Musk and his team involved artificially generated electromagnetic waves and artificially generated electricity. But Vishwakarma was a genius. He wanted to use naturally existing electricity, electromagnetic frequencies, sound resonance and make it much more nature friendly.

Akshayakumara: But how?

Prahasta: You know the story of how Meghnath met Vishnu in Vaikuntha, don’t you?

Trishira: He used brain waves, electricity generated by the body, sound frequencies generated by the vocal chords in combination with a crystal with specific frequencies to match those from Vaikuntha.

Prahastha: Exactly. Vishwakarma used a similar technique.
