Bohr S Model For Hydrogen Atom

The question requires us to find the wavelength of the electromagnetic radiation emitted by a transmitter broadcasting at a frequency of . We are given the speed of light as . We can use the relationship between wavelength, frequency, and the speed of light to find the solution:

Formula: The speed of light ( ) is related to frequency ( ) and wavelength ( ) by the equation:

Step-by-Step Calculation:

1. First, convert the frequency from kilohertz to hertz:
2. Substitute the known values into the formula:
3. Calculate the wavelength:

Conclusion: Therefore, the wavelength of the electromagnetic radiation emitted by the transmitter is approximately 219.3 meters. This matches the given option , which is the correct answer.

Elimination of other options:

• 219.2 m: Very close to the correct answer, but the calculation gives us 219.3 m.
• 2192 m: Incorrect because of a misplaced decimal point.
• 21.92 cm: Incorrect as it's much shorter than the calculated wavelength.

Thus, the correct answer is 219.3 m.
