Question

A note of frequency 200Hz has a velocity of 400m/s. what is the wavelength of the note​

Answer 1

Answer:

$\huge\boxed{\sf \lambda = 2 m}$

Explanation:

Given data:

Frequency = f = 200 Hz

Velocity = v = 400 m/s

Required:

Wavelength = λ = ?

Formula:

v = fλ

Solution:

Put the givens in the formula

400 = (200)λ

Divide 200 to both sides

400/200 = λ

2 m = λ

λ = 2 m
