Answer 1

Answer:

fundamental frequency of vibration of a streached string of length 1m is 256HZ.Find the frequency of the Same string

Answer 2

Explanation:

frequency =

2lν =256×2×1=νNow taking same ν

f= 2lν= 2×0.64

256×2×1

(since length is decreased by 0.36m here length is 1−0.36=0.64m)

=400 Hz.
