Short Answer

When sound passes from one medium to another where its propagation speed is different, does its frequency or wavelength change? Explain your answer briefly.

The wavelength of sound changes and frequency remains constant when sound travels from one medium to another medium.

Step by Step Solution

TABLE OF CONTENTS

Step 1: Relationship of speed of sound , wavelength and frequency

The relationship of speed of sound,wavelength and frequency is given by

v=fλ

Here v is the speed of sound , f is the frequency of waves and λ is its wavelength

Step 2: How wavelength and frequency change when the speed of sound changes.

The Speed of sound changes when sound travels through mediums, but frequency remains constant and hence, wavelength changes. From the formula written above, if the speed of sound will increase, then wavelength will also increase.

(a) At an air show a jet flies directly toward the stands at a speed of \({\rm{1200}}\;{\rm{km/h}}\), emitting a frequency of \({\rm{3500}}\;{\rm{Hz}}\), on a day when the speed of sound is \({\rm{342}}\;{\rm{m/s}}\). What frequency is received by the observers? (b) What frequency do they receive as the plane flies directly away from them?

Air temperature in the Sahara Desert can reach 56.0∘C (about 134∘F). What is the speed of sound in air at that temperature?

What is the approximate sound intensity level in decibels of a \({\rm{600 Hz}}\) tone if it has a loudness of \({\rm{20 phons}}\)? If it has a loudness of \({\rm{70 phons}}\)?

How do sound vibrations of atoms differ from thermal motion?

What frequency is received by a mouse just before being dispatched by a hawk flying at it at \(25.0\;{\rm{m/s}}\)and emitting a screech of frequency\({\rm{3500}}\;{\rm{Hz}}\)? Take the speed of sound to be\(331\;{\rm{m/s}}\).
