Question

what is wavelength of radio wave of frequency 530 MHz (speed of raido wave in air 3×10 to the power 8 m/s)

Answer 1

Hi friend,

We know that,

nu= c/λ

We need to find wavelength,

λ =c/nu

λ = 3×10^8/ 530×10^6

λ =0.005660×10²

λ =0.5660 m.

Hope this helped you a little!!!

Answer 2

The radio wave wavelength is 0.5660 m

Given:

Frequency = 530 MHz

Radio wave speed = 3 × 108 m/s

To find:

Wavelength = ?

Solution:

$\text { Wavelength }=\frac{c}{\nu}$

Where,

c is velocity of light  

n is frequency

$c=3 \times 10^{6} \ \mathrm{m} / \mathrm{s}$

$v=\frac{c}{\lambda}$

We need to find wavelength,

$\lambda=\frac{c}{v}$

Wavelength is a ratio of velocity of light and frequency of the wave. The light has the highest speed.  

$\lambda=\frac{3 \times 10^{8}}{530 \times 10^{6}}$

$\lambda=0.005660 \times 10^{2}$

$\lambda=0.5660 \ m$
