Question

wavelength 0.5cm have a velocity of 340m/s in air. find frequency?​

Answer 1

Hope this helps u
Have a good day

Answer 2

Velocity (V)= 340 ms

Wavelength (λ)= 0.5 cm= 0.005 cm

Frequency (F)= ?

• V=F×λ

340=F×0.005

F=340/0.005

Frequency (F)= 68,000 Hz

Some important definitions:-

⇝Velocity :- It donates the speed of an object in a particular direction.

⇝Types of velocities:-

• Uniform velocity
• Variable velocity
• Average velocity
• Ins tantaneous velocity

⇝Wavelength:- It is the distance between two crests or troughs in a wave.

⇝Frequency:- It specifies the vibration of a wave per second.
