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

a) 1.4 x 10⁵ Hz

b) 1.8 x 10³ Hz

Explanation:

a)

= speed of sound = 342 m/s

= speed of jet = 1200 km/h = 333.33 m/s

= actual frequency = 3500 Hz

= observed frequency

Observed frequency is given as

= 1.4 x 10⁵ Hz

b)

= speed of sound = 342 m/s

= speed of jet = 1200 km/h = 333.33 m/s

= actual frequency = 3500 Hz

= observed frequency

Observed frequency is given as

= 1.8 x 10³ Hz

the answer is a 3.8cm
