Question

find the wavelength if v= 1.7 km\s and frequency= 4.2 MHz

Answer 1

yes I also need the answer plss give

Answer 2

solution: It is quite simple

use the formula Velocity = frequency x wavelength

Given, Velocity = 1.7 km/s = 1.7 x 10³ m/s &
Frequency = 4.2 MHz = 4.2 x 10^6 Hz

Now,
Wavelength = Velocity / Frequency
i.e, Wavelength = (1.7 x 10³) / (4.2 x 10^6) = 404761.9 nano meter
