Influence of the electromagnetic field on the silkworm pulse wave
Object
To study the influence of electromagntic waves with a specific frequency on silkworms
To study the influence of electromagntic waves with a specific frequency on silkworms
Outline of experiment
Place a silkworm parallel to the electromagnetic field lines of the Helmholtz coil and observe the pulse wave changes.
The Helmholtz coil was subjected to an 5V(AC) and a freuency of 14Hz, 21Hz, and 50Hz, respectively.
These frequencies are based on the Schumann resonace that has been reported to have some effect on livng phenomenon.
Pulse waves were detected with a photo reflector and monitored through an amplification circuit
and Arduino with an IDE sketched (programmed) for pulse waves.
