The noble gases can be used to as laser mediums. How is the light from one gas different from light of other gases?

neonofarm [45]

Answer:

light in the UV range.

Explanation:

Noble gases and halogens can combine to form lasers called Excimer, for this to happen the noble gas must be ionized with a high voltage discharge, thus forming a molecule of the type

noble gas (X) + halogen (H) → XH

This molecule is highly unstable and decomposes within a few nanoseconds, emitting light in the UV range.

Charge is distributed uniformly along a long straight wire. the electric field 2 cm from the wire is 20 n/c. the electric field

Serjik [45]

The electric field 4cm from the wire is

$É = 10nc { }^{ - 1}$

Given:

charge is distributed uniformly along a long straight wire.

electric field 2cm from the wire is 20n/c

To find:

electric field 4cm from the wire

what is electric field?

Electric field is the region around charge particle or charged body in which if another charge is placed it experiences electrostatic force.An electric field is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them.

$E ∝ \frac{1}{r}$
