Question

A radio station broadcast on a frequency of 980 kHz. Calculate the wavelength of the electromagnetic radiation.
​

Answer 1

Answer:

306m

Explanation:  

                      ν = c/λ     or

    λ = c/ ν = 3 × 10⁸ ÷ 980 × 10³ = 306m.

Answer 2

$\huge\underline{\colorbox{pink}{Answer:-}}$

• Frequency [v] = 980 kHz

⠀⠀⠀⠀⠀

$:\implies\sf 980 \times 10^{3}$

Using Formula:

$\blue\bigstar\: \: \boxed{\frak{ v = \dfrac{c}{\lambda}}}$

$\underline{\sf{Substituting \ Values \ :}}$

⠀⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

• Now Finding wavelength : ⠀⠀⠀⠀

$\begin{gathered} : \implies\sf v = \dfrac{ 3 \times 10^{8} ms^{-1}}{980 \times 10^{3}} \\\\\\ : \implies\sf \dfrac{3}{98} \times 10^{4} \\\\\ \\ : \implies \underline{\boxed{\frak{{306 \ m}}}} \pink\bigstar\end{gathered}$

• Hence, wavelength of the electromagnetic radiation is 306 m.
