Answer 1

AnsweR :

⠀⠀⠀⠀⠀

⠀⠀⠀$\bullet$⠀Frequency [v] = 980 kHz

⠀⠀⠀⠀⠀

$\leadsto\sf 980 \times 10^{3} Hz$

⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀Using Formula :

⠀⠀⠀⠀

$\star\: \: \boxed{\rm{ v = \dfrac{c}{\lambda}}}$

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

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

⠀⠀⠀⠀⠀Now Finding wavelength : ⠀⠀⠀⠀

$\leadsto\sf v = \dfrac{ 3 \times 10^{8} ms^{-1}}{980 \times 10^{3}} \\\\\\\implies\sf \dfrac{3}{98} \times 10^{4} \\\\\\\implies\boxed{\tt{\purple{306 \ m}}}$

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

Answer 2

$\huge\purple {\mathfrak{Answer:-}}$

The correct answer is 306 m

I hope it helps you!!
