Answer 1

Answer:

a longitudinal wave of wave length 0.03cm travel in air with a speed of 330ms.calucalate the frequency of the wave can this wave be hear by normal

Answer 2

$\huge\red{\boxed{\blue{\mathcal{\overbrace{\underbrace{\fcolorbox{blue}{aqua}{\underline{\red{ANSWER}}}}}}}}}$

Wavelength= 1cm= 0.01m

Velocity= 330 m/s

Frequency= Velocity/Wavelength= 330/0.01= 33000 Hz

33000>20000

Therefore, frequency of this wave is an ultrasound

which heard by a normal human being ear ...
