A radio station broadcasts at a frequency of 590,000 Hz. What is the wavelength of the radio waves?

34kurt

Answer:

f = frequency = 590,000 Hz ===> 59×10^4 Hz

λ = Wavelength = ?

c = Speed of light in a vacuum = 3 × 10^8 m/s

** Hz = 1/sec

___o___o___

$f = \frac{c}{λ} \\ \\ λ = \frac{c}{f} \\ \\ λ = \frac{3 \times {10}^{8} }{590000} \\ \\ λ = \frac{3 \times {10}^{8} }{59 \times {10}^{4} } \\ \\ λ =0.0508 \times {10}^{4} \: m \\ \\ λ = 508 \times {10}^{ - 4} \times {10}^{4} \: m \\ \\ λ = 508 \: m$
