1.	what is the wavelength of a sound wave in air at 20°c with a frequency of 14MHZ? (given V = 3444 m/S)
Answer» Answer: GIVEN, (In air) VELOCITY V=340m/s Frequency f=20,000Hz Wavelegth λ=? V=f.λ λ= F V = 20,000 340 =0.017Hz Also, Given (in WATER) Velocity, V=1480m/s Frequencyf=20,000Hz wavelength, λ=? V=F.λ λ= F V = 20,000 1480 =0.074Hz

what is the wavelength of a sound wave in air at 20°c with a frequency of 14MHZ? (given V = 3444 m/S)

Answer»

Answer:

GIVEN, (In air)

VELOCITY V=340m/s

Frequency f=20,000Hz

Wavelegth λ=?

V=f.λ

λ=

20,000

340

=0.017Hz

Also, Given (in WATER)

Velocity, V=1480m/s

Frequencyf=20,000Hz

wavelength, λ=?

V=F.λ

λ=

20,000

1480

=0.074Hz
