MCQ
Line spectra are due to
- AHot solids
- ✓Atoms in gaseous state
- CMolecules in gaseous state
- DLiquid at low temperature
✓
Answer
Correct option: B.
Atoms in gaseous state
b
Atoms in gaseous state tend to absorb waves of certain wavelength when electromagnetic waves are passed through them. When this light is projected on a photographic film, there are some dark lines caused due to the atoms absorbing waves. This discontinuous spectrum is called line spectrum.

In a radioactive decay process, the activity is defined as $A=-\frac{\mathrm{d} N}{\mathrm{~d} t}$, where $N(t)$ is the number of radioactive nuclei at time $t$. Two radioactive sources, $S_1$ and $S_2$ have same activity at time $t=0$. At a later time, the activities of $S_1$ and $S_2$ are $A_1$ and $A_2$, respectively. When $S_1$ and $S_2$ have just completed their $3^{\text {rd }}$ and $7^{\text {th }}$ half-lives, respectively, the ratio $A_1 / A_2$ is. . . . . . .
