Question

Calculate the wavelength of radio waves of frequency 109 hz. The speed of radio waves is 3 x 108 m s1

Answer 1

I'm assuming there's a typo in "109Hz".

Frequency = $10^9$ Hz

Speed = $3 * 10^8$ m/s

We know, speed = frequency * wavelength (or $c = \nu\lambda$).

So, wavelength is $\frac{3 * 10^8}{10^9}$ m.

Which is equal to 0.3m.

Answer 2

Answer:

0.3 IS THE ANSWER FOR THE QUESTION

Explanation:

I'm assuming there's a typo in "109Hz".

Frequency =  Hz

Speed =  m/s

We know, speed = frequency * wavelength

So, wavelength is  m.

Which is equal to 0.3m.
