RELATIONSHIP BETWEEN WAVELNGTH , WAVEVELOCTY , FREQUENCY .
NO GO0GLE ANSWERS ^_^

Answer 1

✯Question✯

• Relationship between wavelength , wave velocity , frequency.

✬Answer✬

• Let velocity of a wave be V , time period be T , frequency be f and wavelength be λ.
• Wavelength (λ) = Distance travelled by the wave in one time period
• Wavelength (λ) = Wave velocity × Time period
• Wavelength (λ) = V × T
• VT = λ
• But , we know , T = 1 ÷ f
• T is time period , f id frequency.
• So, V × 1 ÷ f = λ
• V = fλ

➺Wave velocity  = Frequency × Wavelength  (V = fλ)

Answer 2

Let velocity of a wave be V , time period be T , frequency be f and wavelength be λ.

Wavelength (λ) = Distance travelled by the wave in one time period

Wavelength (λ) = Wave velocity × Time period

Wavelength (λ) = V × T

VT = λ

But , we know , T = 1 ÷ f

T is time period , f id frequency.

So, V × 1 ÷ f = λ

V = fλ
