A source is moving towards an observer with a speed of 20 \( \mathrm{m} / \mathrm{s} \) and having frequency of \( 240 \mathrm{~Hz} \). The observer is now
\( \mathrm{P} \) moving towards the source with a speed of \( 20 \mathrm{~m} / \mathrm{s} \). Apparent frequency heard by observer, if velocity of sound
W is \( 340 \mathrm{~m} / \mathrm{s} \), is
