2 Points
The speed of a radio wave is 3 x 108 m/s. The wave has a frequency of 9.98 x
10' Hz. Use the wavelength equation to calculate the wavelength.
O A. 2.5x 10-4 m
O
B. 2.99 x 1016 m
O c. 4.4 x 105 m
O D. 3 m

Respuesta :

Answer:D

Explanation:

Let [tex]l[/tex] be the wave length of the given wave.

Let [tex]v[/tex] be the speed of the given wave.

Let [tex]f[/tex] be the frequency of the given wave.

As we know,

[tex]l=\dfrac{v}{f}[/tex]

Given,

[tex]v=3\times 10^{8}ms^{-1}\\f=9.98\times 10^{7}Hz[/tex]

So,[tex]l=\frac{3\times 10^{8}}{9.98\times 10^{7}}=3m[/tex]
