What type of spectrum is produced by a hydrogen gas when a high potential difference is applied to it?



a visible spectrum

emission spectrum

absorption spectrum

a continuous spectrum

I've been all through my notes and cant figure this one out :/

That doesn't help me beytotch

To determine the type of spectrum produced by a hydrogen gas when a high potential difference is applied to it, we can go through the options and eliminate the incorrect ones.

1. A visible spectrum: This option is vague because all spectra, except for completely dark spectra, are visible. So, we can eliminate this option.

2. Emission spectrum: When a high potential difference is applied to a hydrogen gas, it excites the gas atoms, causing the electrons to transition from a higher energy level to a lower energy level, releasing energy in the form of light. This emitted light is known as an emission spectrum. Therefore, this option is correct.

3. Absorption spectrum: An absorption spectrum is produced when a substance absorbs specific wavelengths of light from a continuous spectrum. However, in this case, we are applying a high potential difference, which causes the hydrogen gas to emit light rather than absorb it. Therefore, we can eliminate this option.

4. A continuous spectrum: A continuous spectrum consists of an uninterrupted range of wavelengths. In the case of a hydrogen gas with a high potential difference, it produces specific bright lines of light, rather than a continuous range of wavelengths. Hence, we can eliminate this option.

Therefore, the correct answer is an "emission spectrum."

An emission spectrum will be produced. Some, but not all, of the radiation emitted will be visible.
