Question

pls answer me fast

in the given figure if velocity of wave is 400 m/s. if the time period of the wave is n/400 sec. then find n​

Answer 1

Answer:

Displacement = velocity × time

Step-by-step explanation:

Let displacement is x

Velocity= 400m/s

Time=400sec

Displacement= 400×400=1600m

n=1600m

Answer 2

Step-by-step explanation:

velocity = wavelength*frequency

from graph wavelength=50+50 =100 cm

400 = 1*frequency

frequency = 400 Hz

also frequency = 1/(periodic time)

periodic time = 1/400

but it is given periodic time = n/400

therefore, n/400 = 1/400

hence n= 1
