The sound needs medium (gås, liquid or solid) to travel. In the first case, the sound became fainter because the air (medium) is sucked up.
In the second case, when sucking of air was stopped, sound became louder again, as the air remained intact this time.
Yes, the decrease in air (medium) volume was the reason for decreasing loudness of the sound.
In the second case, when sucking of air was stopped, sound became louder again, as the air remained intact this time.
Yes, the decrease in air (medium) volume was the reason for decreasing loudness of the sound.

Direction. In the following questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : When an iron rod is inserted into a coil connected to a bulb in an a.c. circuit, the glow in the bulb decreases. Reason : The current in the coil increases, thereby decreasing current through the bulb
