WAEC SSCE - Physics - 1994 (Objective)

Question 1 Report

A note of frequency of 2000Hz has a velocity of \(400ms^{-1}\). What is the wavelength of the note?
Answer Details
The formula for calculating wavelength is: wavelength = velocity/frequency In this question, the frequency is given as 2000Hz and the velocity is given as 400m/s. Substituting these values into the formula, we get: wavelength = 400/2000 wavelength = 0.2m Therefore, the wavelength of the note is 0.2 meters.
