Question 1 of 10

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

Answer 1

Answer:D

Step-by-step explanation:

Let
`l` be the wave length of the given wave.

Let
`v` be the speed of the given wave.

Let
`f` be the frequency of the given wave.

As we know,

`l=(v)/(f)`

Given,

`v=3* 10^(8)ms^(-1)\\f=9.98* 10^(7)Hz`

So,
`l=(3* 10^(8))/(9.98* 10^(7))=3m`
