Q:

Bright light is found to emit from photographer’s flashgun. This brightness is due to the presence of which one of the following noble gases?

A) Argon B) Xenon
C) Neon D) Helium
 
Answer & Explanation Answer: B) Xenon

Explanation:

Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.
