Definitely. The electric field doesn't need any substance there
to carry it from one place to another.

Why light can pass through empty space?
Basically, light is NOT a mechanical wave, which would require matter; it is an electromagnetic wave, which means that disturbances in the electric field and the magnetic field propagate. This requires no matter; such fields exist - and can propagate - in empty space.
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
Which wave cannot exist inside wave guide?
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
When electric and Fields both exist it's called electromagnetic field?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.

How an electromagnetic wave can travel throught space that contains no matter?
The wave is a disturbance in the electric and magnetic field in space. These fields exist even in empty space.

Does an electric field exist outside a parallel plate capacitor?
Electric fields exist everywhere there is an electrical potential difference between one place and another. A simple radio antenna has an alternating electric field from one end of an element to the other.
When and magnetic fields both exist it is called an electric magnetic field?
electromagnetic

Where is the electric field in conducting and non-conducting sheets?
E field does not exist within the conductor, because the charge exists on the surface. This is not true for non conductors.
How is light self-propagating?
Light is self-propagating because it consists of electromagnetic waves that do not need a medium to travel through. When an electric field changes, it generates a magnetic field, which in turn generates an electric field and so on, creating a self-sustaining wave that can travel through empty space.

Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
