Question

1. A radio station transmits waves of wavelength 200m. If the speed of
waves is 3 x 108 ms", find the frequency of the radio station.​

Answer 1

Answer:

• 1.5 × 10⁶ Hz

Explanation:

Given:-

• Wavelength , λ = 200 m

• Speed of wave ,s = 3×10⁸m/s

To Find:-

• Frequency of the radio Station ,f

Solution:-

As we have to calculate the frequency of the radio Station .

using formula

• f = s/λ

Where,

• f denote frequency
• s denote speed of light
• λ wavelength

Substitute the value we are

→ f = 3×10⁸/200

→ f = 1.5 ×10⁶ Hz

• Hence,the frequency of the radio wave is 1.5×10⁶ Hz

Answer 2

Answer:

Given :-

• Wavelength = 200 m
• Speed of waves = 3 × 10⁸ m/s

To Find :-

Frequency

Solution :-

$\huge \bf \: F = \dfrac{ s}{ \lambda}$

F = 3 × 10⁸/200

F = 1.5 × 10⁶ Hz

Hence :-

The frequency of radio at that wavelength is 1.5 × 10⁶ Hertz
