Vedclass · Answer

(D) burning candle emits a continuous spectrum because it contains a wide range of wavelengths.Sodium vapour emits a characteristic line spectrum due to electronic transitions.$A$ Bunsen flame often shows a band spectrum due to molecular emissions.Dark lines in the solar spectrum (Fraunhofer lines) are caused by the absorption of specific wavelengths by gases in the solar atmosphere,forming an absorption spectrum.Therefore,the correct matching is $1-(ii), 2-(i), 3-(iii), 4-(iv)$.

$1$. Burning candle	$i$. Line spectrum
$2$. Sodium vapour	$ii$. Continuous spectrum
$3$. Bunsen flame	$iii$. Band spectrum
$4$. Dark lines in solar spectrum	$iv$. Absorption spectrum

Match the following:
$1$. Burning candle $i$. Line spectrum
$2$. Sodium vapour $ii$. Continuous spectrum
$3$. Bunsen flame $iii$. Band spectrum
$4$. Dark lines in solar spectrum $iv$. Absorption spectrum
