  The study of novae is continued and a self-consistent updated physical model
for classical/recurrent novae derived from multi-wavelength observations is
presented. In particular, observations of novae support the origin of the
optical continuous emission in the outburst ejecta, mass-based segregation and
clump formation in the ejecta, origin of the Orion, diffuse enhanced lines and
dust in the clumps, prompt Fe II line formation in swept-up material,
energising of electrons to relativistic velocities by the explosion and the
existence of a large cool envelope around the accreting white dwarf in
quiescence. The rapid transfer of thermonuclear energy should be adiabatic
which energises and ejects all the particles in the overlying layers. Our study
results in the following conclusions which are relevant for novae and other
astrophysical systems: (1) Electrons are instantaneously energised to
relativistic velocities in the explosion alongside the heavier atoms and ions.
No post-ejection shock acceleration needs to be invoked. (2) Rotation of an
incompressible spherical accreting object leads to a latitude-dependent
potential such that the accretion rate is maximum at the poles and minimum at
the equator. This will form a prolate-shaped envelope. Energetic expulsion of
this envelope will result in a bipolar ejecta/outflow. Such outflows cannot be
ejected from non-rotating spherical objects. (3) The latitude-dependent
accretion rates in a rotating accreting object will also lead to accumulation
of the infalling matter outside the object in the non-polar regions thus
forming an accretion disk. The angular momentum of the incoming matter plays no
role in the formation of an accretion disk. Accretion disks cannot form around
a non-rotating object.
