Question

A tuning fork makes 256 vibrations per second in air. When the velocity of air is 330m/s then wavelength of time emmited is

Answer 1

wave length = speed of sound / frequency

                    = 330 / 256

                    = 1.28 m

Answer 2

Answer:

1.29 m

Explanation:

hey mate!

given:

frequency of the tuning fork(f)=256 Hz

velocity of sound in air(v)=330 m/s

wavelength of sound wave(lambda)=?

we know the relation,

v=f*lambda

=>lambda=v/f

=>lambda=330/256=1.29 m

some additional information:

tuning fork is an instrument which is used to produce vibration of fixed frequency.commonly used tuning fork are 256Hz and 512 Hz.it consists of two arms known as prongs...
