Change in temperature of the medium changes

1. frequency of sound waves

2. amplitude of sound waves

3. wavelength of sound waves

4. loudness of sound waves

(3) Hint: The speed of the sound waves depends on the temperature of the medium.
Step 1: Find the speed of the sound waves in terms of temperature.
Speed of sound wave in a medium, νT (where is the temperature of the medium)
Clearly, when temperature changes, the speed also changes.
Step 2: Find the variation in the frequency and the wavelength.
As,                                     ν=νλ                                  
where v is the frequency and λ is the wavelength.
Frequency (ν) remains fixed,
                                            νλ  or  λν                              
As the frequency does not change, so the wavelength (λ) changes.
