the wavelength of a wave is 1.7 multiplied by 10 to the power -2.(1.7 *(10^(-2)). The speed of the wave is 343.4 m/s.

Find frequency and time period.

Open in App

Solution

Frequency = Velocity / Wavelength
f= (343.4 m/s) / (1.2 × 10⁻² m)
= 28.6 × 10³ Hz
= 28.6 kHz
time period,T=1/f
T=1/(28.610^3)
=3.4910^-5 sec
