Question

131. As temperature increase, difference between
apparent doppler frequency and actual frequency
(1) Decreases
(2) Remains unchanged
(3) Increases
(4) Depending on frequency, increase or decrease.​

Answer 1

Answer:

As the temperature increases ,difference between apparent Doppler frequency and actual frequency Decreases(1)

Explanation:

As the temperature increases difference between apparent Doppler frequency and actual frequency decreases because as we know that the  Speed of the sound is directly proportional to the square root of temperature.So the  actual frequency of sound does not depend on change with the temperature
