Question

Two waves C&D have amplitude 1cm and
1.5cm respectively. time period of wave C is
0.5 sec while time period of D is 0.65 sec.
(1) Which sound in louder ? Give reason.
(2) which sound is shriller? Give reason​

Answer 1

Answer:

1) Wave D will be more louder than wave C

2) Wave C will be more shriller than wave D

Explanation:

1) As the wave D has more amplitude as compared to wave C...that's why higher the amplitude ..louder the sound...

2) As the frequency of wave C is 2 Hz and the frequency of wave D is 1.53...that's why higher the frequency ...higher will be the shrillness.
