    Let lambda
    be the radius of the particle then
    λ=3×10−4×10−²m=3×10-⁶m
    Frequency of electromagnetic wave,
    υ

    10
    8
    3
    ×
    10

    6
    =
    10
    14
    Thus to obseve the particle, the frequency of wave should be more than
    10
    14
    i.e
    10
    15
    Hz or smaller value of wavelength. 42:30

    @adriangheorghe2327 Год назад +1

    The so-called UE electromagnetic waves exist only in conductors. In the cosmic vacuum, materialized by the etheric, non-cohesive, non-inertial, inelastic and incompressible ocean, i.e. in the ocean of weightless matter, the wave mechanism, which requires the successive transformation of one form of energy into another, cannot function. The phasing of the electric field with the magnetic field in the breast of EM waves is clear evidence that the wave mechanism does not work in a vacuum. The so-called electromagnetic waves are just some electromagnetic reliefs, made up of the chained circulations of the electric and magnetic fields. After deciphering the physical meaning of the action constant h, it can be demonstrated that at the level of each half-wave, the propulsive electromagnetic force is in balance with the inertial force, (BIl=m.a). This balance makes the sliding (translation) with a uniform rectilinear speed, of the scalar structure of the electromagnetic wave. The uniform-rectilinear speed and the transversal periodic structure give the wave appearance of E-M radiation. But the E-M radiation is only a dynamic structure similar to the linear electric motor, which glides through the vacuum at the speed of light, being propelled by the electromagnetic force, the force which is in balance with the inertia force.
