Question

Explain Hertz's experiment related to electromagnetic waves.

Answer 1

Hint: In ordered to answer this question we must know about the electromagnetic waves concept. The frequency of electromagnetic waves naturally equals the frequency of oscillation of the charge.
Tools require: In this experiments we used-
Two equal sizes of metals plates.
Two metal sphere
Copper wire.

Complete step-by-step solution:
At first we placed two metal plates A and B at a distance of $$60cm$$. Connected them with two polished metal spheres S1 and S2 and an induction coil placed between a small gap of two spheres.
As we know due to high potential across S1 and S2 the air within the little gap between the spheres gets ionized and provides a path for the discharge of the plates. A spark is created between S1 and S2 & magnetism waves of high frequency area units radiated. Hertz’s was ready to manufacture magnetism waves of frequency . Here the plates A and B act as a electrical devices having little capacitance worth C and also the connecting wires give low inductance L. The oscillation of charges between two plates is-
$$v={\displaystyle \frac{1}{2\pi \sqrt{LC}}}$$

Note: The experiments based on the theory of oscillating electric charge radiates electromagnetic waves. Maxwell’s electromagnetic wave theory was proved by Hertz's experiments in 1888.
