TITLE: Concerning an approximation in the theory of propagation of ordinary waves

ABSTRACT: From the known expression Tor the refractive index of the ordinary wave
in a uniform magnetized plasma when collisions, ion motions, and space dispersion
are neglected, the author shows that when the following condition is also satisfied,

notic field, the phase velocity~ia c,cos a (o is the velocity of light in vacuo)
and tho group velocity is accordingly in the direction of the magnetic field and of
magnitude c. Thij is reminiscent of the behavior of Alfven wavea, the group veloci-

for large values of d the angle between the group velocity and the magnetic field
never exceeds 190 291. It is suggested that tile circumstances noted above may find

rcsttltr can throw light on the origin of different types of Y1f radiation, and t1~at
there are i-mportant grounds for assuming that this radiation is produced by hi&,
Onei-1.3, particles in the earth's outer radiation belt and In the aurora zones. There
are also reasons for assuming that the vlf radiation plays an Aqw-tant rcde in the

waves in the corona is quite possible. Thdkpossibility of the longitudinal
waves becoming transformed into transverse ones is considered, as are the
conditions under which the radio waves can leave the corona. If waves propa-
gate in plasm located in a magnetic field, the radiation may be "sucked
outs-' from the corona region (taking into account the thermal motion of the
electrons). If the plasma wave propagates at an angle to the direction of
the gradLient of the electron concentration, the radio waves may leave the
corona also in the absence of maMatic fields. Such a wave may be produced
under the influence of an external agent. I~ the action of the agent is of
short duration, the radio waves will also last a shai-t time (type III of ra-
diation ). Radiation of type IV is apparently produced by streams of fast
particles, which excite plasma waves. The works in which the drift of the
plasma is believed to be the energy source causing the growth of the waves
Is criticaUy reviewed,, In the discussions, I.S. Shklovskiy emphasized that
the reslilts of the observations indicate that na,one mechanism is capable of
explaining all t7
.pes of radio waves, although most pheacmena are apparently
dte to plasma oscillations. V.L. Ginzburg indicated the difference between
the mechanisms of radiation of relativistic electrons from the galaxy and
from the sun; in the former casethe angle between the electron velocity and
the magnetic field iu large, and in the second case it is 5mall. Biblio-

Abstract: Discussion of the problem of the effect of the magnetic field on the
occurrence of convection of an electron-ion plasma under conditions
where the effect of the anisotropy of the electric conductivity, the
heat conductance, and the viscosity exert a substantial influence.
The work is a continuation of a preceding cne (Referat Zhur - Fizika,
1956, 36224), in which only the anisotropy of the electric comduc-
tivity and of the heat conductivity are taken into account. Two
particular cases are considered: when the dixection of the pe=a-
nent magnetic field is the same as the direction of the acceleration

It is shown that in the latter case the occurrence of convection is
facilitated substantially both because of the effect of an�sot~i-jpy

At first some works dealing with this subject are cited. However, on this
ocoasion the author deals only with a paper by J.H.PIDDINGTON, Phil.Mag.46,
1037 (1955) on high-frequent waves (ordinary and extraordinary waves, plasma
waves). The author endeavors to clear up the connection between the various
types of normal waves with greater accuracy than this was done by PIDDINGTON.
At first an equation is derived from the equations of electrodynamics and from
the quas.-Lhydrodynamic equations of motion in consideration of electron pres-
sure, and this equation is investigated for the nonrulativistic case
