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 ${\boxed{\blue{\checkmark{}}}}$

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
