Question

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

Answer 1

Answer:

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
