Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet.
In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
What else can I help you with?
What are properties of positive rays?
Properties of positive rays:*Anode rays travels in a straight line.*It has positive charge.*They consists of material particles.*These particles which have a mass 1836 times that of the electrons are known as protons
How many sets does an angle separate a plane?
An angle separates a plane to 3 sets: 1) Points between the 2 rays 2) Points on one of the rays 3) Points outside of the 2 rays
How many points do rays have?

In what branch of math do you learn about rays points chords and line segments?
Geometry teaches points, lines, rays, chords and segments.
Who is positive rays inventor?

How points can opposit rays have in common?
One
In which direction do electric field points from positive to negative?
The electric field points from positive to negative.
How does the mass to charge ratio of cathode rays compare to that of anode rays?
it varies because charge to mass ratio of positive rays depends upon gases used in the discharge tube.its varies from gas to gas.
How many points can opposite rays have common?
One
Do opposite rays have common end points?
maybe
Does alpha rays contains only a positive charge of atom?
Alpha rays are helium ions, He2+.
Why anode rays also known as canal rays?
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
