Answer:
The frequency of sound wave created by trumpet is 437.5Hz
Explanation:
Given 
the speed of sound wave = 350 m
the wavelength of sound wave = 0.8 m
the frequency of sound wave = ?
All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:
v = fλ, where
v is speed of the wave
f is frequency of the wave
λ is wavelength of the wave
therefore frequency of sound wave is given by
f = v/λ
  = 350m /0.8m
/0.8m
  = 437.5
  = 437.5Hz (since 1  = 1 Hz (Hertz)
 = 1 Hz (Hertz)
Hence the frequency of sound wave created by trumpet is 437.5Hz
 
        
             
        
        
        
Answer:
0.0000109261200583 s
0.0109261200583
Explanation:
 = Distance from right ear = 3 m
 = Distance from right ear = 3 m
s = Distance between ears = 15 cm
v = Speed of sound in air = 343 m/s
Distance between the left ear and the bird

Time

Time difference would be

The time difference is 0.0000109261200583 s
Time period is given by

The ratio is

The ratio is 0.0109261200583
