Question

a sound wave of frequency 640Hz travels 800m in 2.5 sec.calculate:speed of sound and wavelength of sound wave

Answer 1

hey there is answer !!



Dear student,
Here is the solution of your asked query:
Frequency, f=640 hzDistance travelled = 800 mTime taken, t= 2.5 secondsSo, speed of sound = 8002.5=800×1025=320 m/sAnd wavelength =speed frequency=320640=12 m
Regards

Answer 2

Topic: Sound

• Speed of the Sound  wave = Distance traveled/Time taken

                                                     =800/2.5

                                                     = 320 m/s   (wavespeed)

• Wavelength of Sound = Wavespeed / Frequency

                                             = 320/5

                                             =64  λ .
