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
