Question

A certain radio station broadcasts at a frequency of 980 khz what is the wavelength

Answer 1

f=980×10^3 hz

V=f(lemda)

lemda=v/f

lemda=3×10^8/980

Answer 2

Answer:

AnswEr :

⠀⠀⠀⠀⠀

⠀⠀⠀$\bullet$⠀Frequency [v] = 980 kHz

⠀⠀⠀⠀⠀

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

⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀Using Formula :

⠀⠀⠀⠀

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

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

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

⠀⠀⠀⠀⠀Now Finding wavelength : ⠀⠀⠀⠀

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

Hence, wavelength of the electromagnetic radiation is 306 m.
