s What is the wavelength of an electromagnetic wave if it has a frequency of 5.10 x 10 9H2?​

Answer:

The wavelength is 0.59 x [tex]10^{-1[/tex] m.

Solution:

  • First, let write the given.

frequency = f = 5.10 x 10^9 Hz

velocity = v = 3 x 10^8 m/s

wavelength = w = ?

  • Then, substitute the given in the formula.

[tex]w=\frac{v}{f}[/tex]

  • Then simplify.

[tex]w=\frac{3*10^{8} }{5.1*10^{9} } \\w=0.59*10^{8-9} \\w=0.59*10^{-1}[/tex]

  • What is the unit?

[tex]frequency=Hertz=\frac{1}{second}\\velocity=meter/second\\wavelenght=?\\\\\\wavelenght=\frac{velocity}{frequency}\\wavelenght=\frac{meter/second}{1/second} \\wavelenght=(\frac{meter}{second} )second\\wavelenght=meter=m[/tex]

  • Thus, the final answer is 0.59 x [tex]10^{-1[/tex] m (meter)

Hope it Helps!
