Question

If the velocity of radio waves is 3×10^5 km/s, the
frequency corresponding to wavelength of 300 m is​

Answer 1

Answer:

Frequency is $10^6 Hz$

Explanation:

Velocity of radio waves is $c=3\times10^5 km/s=3\times 10^8 m/s$

Wavelength  λ= 300 m

We know wavelength

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

the frequency is

$f=\frac{c}{\lambda} \\\\f=\frac{3\times 10^8}{300} \\\\f=10^6 Hz$
