Radio waves are used to transmit information on various channels. What is the wavelength of a radio wave having the frequency of 5.40 × 1010 Hz? 1. Analyze the Problem

ν = and c = Unknown: λ =

You know that because radio waves are part of the electromagnetic spectrum, their speed, frequency, and wavelength are related by the formula c = λν.

5.56×10¯³ m

Explanation:

From the question given above, the following data were obtained:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

The velocity of electromagnetic wave, frequency and wavelength are related according to the equation:

Velocity (c) = wavelength (λ) × frequency (v)

c = λv

With the above formula, the wavelength of the radio wave can be obtained as follow:

Frequency (v) = 5.4×10¹⁰ Hz

Wavelength (λ) =?

Velocity (c) = 3×10⁸ m/s

c = λv

3×10⁸ = λ × 5.4×10¹⁰

Divide both side by 5.4×10¹⁰

λ = 3×10⁸ / 5.4×10¹⁰

λ = 5.56×10¯³ m

Thus, wavelength of the radio wave is 5.56×10¯³ m

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
