Answer 1

⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐


⚡ FREQUENCY - The number of oscillations made by a vibrating body in one second is called its frequency.

⚡ WAVELENGTH - Length of one wave is called wave length.

⚡ TIME - The time taken for a particle of medium to complete its one oscillation is called "time" or ''time period".



==================================

Here, first we have to note the given datas.

[ S O L U T I O N ]


✔ FREQUENCY (f) = 4 kHz = 4000 Hz.

✔ WAVELENGTH (W) = 40 cm = 0.4 m

✔ NOW, WAVE VELOCITY (V) = f × W
=> V = (4000 × 0.4) m/s = 1600 m/s.

✔ So, DISTANCE = 3.2 km = 3200 m.
SPEED = 1600 m/s (WE ALREADY GET).

✔ TIME = (3200/1600) second = 2 second.

Thus, the above numerical is solved.
