Question

If speed is 180 ms-1 and frequency is 200 Hz, The wavelength should be​

Answer 1

ANSWER:

• As frequency is 200Hz, that means 200 waves are produced on one second.

• So, time taken to produce 150 waves = 200/150 =0.75s

• Velocity of wave = Frequency × Wavelength =200×1580=30000 cmps =300 meters per second

So, Distance =300×0.75=225 cm

Answer 2

Answer:

speed = 180m/s

frequency = 200Hz

wavelength = velocity / frequency

$wavelenght \: = \frac{180}{200} = 0.9meter \:$

so the wave length is 0.9 meters
