Answer:
If the ruler is plucked while it is held with 25 cm of it off the table, does it make any sound? If there is no sound, look for the reason;
After placing the ruler with 25cm of it on the table and 5cm in air...
When we vibrate, we may notice that number of vibrations produced by 25cm blade is less.
As pitch of sound depends upon frequency
so, frequency is less and hence pitch of sound is low and hence low pitch sound is produced by blade.
conclusion:
More is shrillness of sound more is the pitch and it has more frequency.
