Question

1. How is the frequency of a wave measured?​

Answer 1

Answer:

Wave frequency can bemeasured by counting the number of crests or compressions that pass the point in 1 second or other time period. The higher the number is, the greater is the frequency of the wave. The SI unit forwave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second

Answer 2

Answer:

frequency can be measured by..

$f = 1 \div \: lameda$

here lameda = wavelength
