Answer 1

$\red\maltese$Given :

$\:\:\:\:\:\:$

• $\sf\dashrightarrow\:Wavelength \:[λ] \:= \:200$

$\:\:\:\:\:\:$

• $\sf\dashrightarrow\:Speed\: of \:wave \:[s] \:=\: 3×10⁸m/s$

$\:\:\:\:\:\:$

$\blue\maltese$To Find :

$\:\:\:\:\:$

• $\sf\dashrightarrow\:The\: radio \:Station\: Frequency$

$\:\:\:\:\:\:$

$\orange\maltese$Formula Used Here :

$\:\:\:\:\:\:$

• $\large\sf\implies\red{\boxed{\:f\:=\:\dfrac{s}{λ}}}$

$\:\:\:\:\:\:$

$\green\bigstar$Understanding the concept :

$\:\:\:\:\:\:$

• For solving this question we have to first understand the concept of frequency. we have to apply formula f = s/λ.After putting value in formula we can easily calculate frequency of radio station .

$\:\:\:\:\:\:$

$\red\dag$So let solve Further !

$\:\:\:\:\:\:$

$\blue\maltese$ Putting the value in Formula :

$\:\:\:\:\:\:$

• $\large\sf\implies\green{\:f\:=\:\dfrac{s}{λ}}$

$\:\:\:\:\:\:$

• $\sf\implies\pink{\:f\:=\:\dfrac{3 × 10⁸}{200}}$

$\:\:\:\:\:\:$

• $\sf\implies\red{\:f\:=\:1.5 × 10⁶\:hz }$

$\:\:\:\:\:\:$

$\sf\longmapsto\purple{\underline{\underbrace{\underbrace{Hence,\:the \:frequency \:of \:the \:radio\: wave\: is \:1.5×10⁶ \:hz}}}}$

$\:\:\:\:\:\:$
