The assertion is incorrect while the reason is correct. Sound actually travels faster in humid air compared to dry air. This is because water molecules are lighter than the oxygen and nitrogen molecules that make up the air. When the air is humid, there are more water molecules and fewer oxygen and nitrogen molecules. Since sound travels faster in lighter gases, it travels faster in humid air.

However, the reason is correct in stating that the density of air increases when moisture is present. But this doesn't slow down the speed of sound, it actually increases it.
