Question

Would you use a tungsten or a deuterium lamp as a source of 300-nm radiation? What kind of lamp provides radiation at 4-mm wavelength?

Short answer

We would use a deuterium lamp as a source of 300-nm radiation.

Silicon carbide globar lamp provides radiation at wavelength.

Step-by-step solution

Step: 1 Explanation of tungsten lamp, deuterium lamp and radiation:

Radiation is the release of energy, whether it is in the form of waves or particles.

A deuterium lamp emits light in the near ultraviolet and ultraviolet regions from 150 nm to 400 nm.

Tungsten lamp, a lamp in which light is produced by a tungsten filament heated to incandescence by an electric current.
