Answer 2

${\huge{\underline{\underline{\mathcal{\red{♡ANSWER♡}}}}}}$

• ⭐The$\pink{\tt{Wavelength}}$ λ,is equal to $\red{\tt{c}}$/$\purple{\tt{v}}$.
• ⭐where $\green{\tt{c}}$ is the speed of $\red{\tt{electromagnetic radiations in vaccum}}$ and $\blue{\tt{v}}$is the $\purple{\tt{frequency substituting}}$ .
• ⭐The given values ,we have

• ⭐ λ = c/v
• ⭐$\frac{3.00×10^8ms^-1}{1368kHz}$

• ⭐$\frac{3.00×10^8ms^-1}{1368×10^3s/-1}$
• ⭐${219.3m}$
