Question

A wave of wavelength 0.68m has a time period of 0.002s. Find its velocity.​

Answer 1

Explanation,

Given,

• Wavelength (λ) = 0.68 m
• Time period (T) = 0.002 s

To Find,

• It's velocity.

Solution,

Firstly, we need to find "Frequency".

We know that,

f = 1/T

Where,

• f = Frequency
• T = Time Period

[ Put the values ]

⇒ f = 1/0.002

⇒ f = 500 hz

Now, velocity

We know that,

v = λ × f

[ Put the values ]

⇒ v = 0.68 × 500

⇒ v = 340 m/s

Therefore,

The velocity of a wave is 340 m/s.
