The Vividh Bharti station of All India Radio, Delhi, broadcasts on frequency of 1368 kHz (kilo hertz). The wavelength emitted by the transmitter is

The Vividh Bharti station of All India Radio, Delhi, broadcasts on a frequency of 1368 kHz (kilohertz). To determine the wavelength emitted by the Vividh Bharti transmitter, we use the relationship between wavelength (λ), speed of light (c), and frequency (v):

Formula: λ = c / v

Substituting the Values

• The speed of light (c) is constant at 3 × 10⁸ m/s.
• The frequency (v) is given as 1368 kHz.
• Since 1 kHz equals 10³ cycles per second, we convert the frequency to 1368 × 10³ Hz.

Thus, v = 1368 × 10³ s^-1.

Calculating the Wavelength

Using the formula:

λ = c / v

Substituting the values:

λ = (3 × 108 m/s) / (1368 × 103 s-1)

Performing the calculation:

λ = 219.3 m

Conclusion

The wavelength of the radio waves emitted by the Vividh Bharti station transmitter is approximately 219.3 meters. These waves fall in the radio wave region of the electromagnetic spectrum, which is commonly used for long-distance broadcasting like Vividh Bharti.
