A wave of wavelength 52 cm travels with frequency 400 Hz. What is the speed of the wave? Show all work

208 m/s

Explanation:

Given,

frequency = 400Hz

wavelength = 52cm

we need to convert cm to m

52 cm/100cm {1m=100cm}

=0.52m

wkt,

wavelength = speed of wave/frequency

to find speed of wave

speed of wave=frequency * wavelength

=400 * 0.52

=208 m/s
