Question

If the time period of an ocean wave is 10s and its velocity 15 m/s then what will be the value of its wavelenth

Answer 1

$\Large\underline{\underline{\sf Given:}}$

• Time period (T) = 10s

• Velocity (v) = 15m/s

$\Large\underline{\underline{\sf To\:Find:}}$

• Value of Wavelength = ?

$\Large\underline{\underline{\sf Formula\:Used:}}$

$\large{\boxed{\boxed{\sf \pink{\lambda=\dfrac{v}{f}}}}}$

$\large{\boxed{\boxed{\sf \pink{f=\dfrac{1}{T}}}}}$

$\Large\underline{\underline{\sf Solution:}}$

$\Large\implies{\sf \dfrac{1}{T}}$

$\implies{\sf f=\dfrac{1}{10} }$

$\Large{\sf \lambda=\dfrac{v}{f}}$

$\implies{\sf \lambda=15×10 }$

$\implies{\sf \lambda=150\:m}$

$\Large\underline{\underline{\sf Answer:}}$

⛬ Wavelength is 150m
