Two bodies A and B are made to vibrate in such a way that Body A vibra

1.	Two bodies A and B are made to vibrate in such a way that Body A vibrates 10 times in a second and Body B vibrates 120 times in 1 minute. A) Which body would produce a shriller sound and why? B) How is the pitch of sound related to its frequency? C) Write an activity to show effect of frequency on the pitch of sound
Answer» en: Two bodies A and B are made to vibrate in such a way that Body A VIBRATES 10 times in a second and Body B vibrates 120 times in 1 minute. To find: Which body PRODUCES shriller SOUND? How is pitch related to frequency? Activity to show this effect. Solution: Frequency of body A = 10/60 = 0.16 Hz Frequency of body B = 120/60 = 2 Hz Since , Body B has higher frequency, it will produce a shriller (high pitched) sound than Body A. Frequency is directly proportional to the pitch. Higher the pitch , higher will be frequency , higher will be the shrillness of the sound. Experiment: Go to physics lab of your school. Take two tuning forks of different frequencies (e.g. 256 Hz and 512 Hz) MAKE the forks vibrate by hitting it on a cork plate. Bring the vibrating fork near your ear. You will be ABLE to understand this effect of frequency and pitch. 512 Hz tuning fork will produce high pitched sound than 256 Hz fork. $\star$ HOPE IT HELPS.

Two bodies A and B are made to vibrate in such a way that Body A VIBRATES 10 times in a second and Body B vibrates 120 times in 1 minute.

Frequency of body A = 10/60 = 0.16 Hz

Frequency of body B = 120/60 = 2 Hz

Since , Body B has higher frequency, it will produce a shriller (high pitched) sound than Body A.

Higher the pitch , higher will be frequency , higher will be the shrillness of the sound.
