Question

What is the wavelength of radio waves? A. between 1 x 10-3 and 1 x 10-1 meters B. less than 1 x 10-11 meters C. more than 1 x 10-1 meters D. between 1 x 10-8 - 4 x 10-7 meters E. between 4 x 10-7 - 7 x 10-7 meters

Answer 1

More than 1 × 10⁻¹ meters

Step-by-step explanation:

Wavelength is defined as the distance between the successive crests and the successive trough of a wave.

Radio waves are the type of electromagnetic radiation that have longest wavelength in the electromagnetic spectrum. This wave travel with the speed of light. The wavelength of radio waves is 10³ meters.

So, the wavelength of radio waves i.e. more than 10⁻¹ meters. Hence, the correct option is (c).

Answer 2

The correct answer option is C. more than 1 x 10-1 meters.

Step-by-step explanation:

A wavelength is the distance between the successive crests of a wave.

A type of electromagnetic (EM) radiation is called radio waves which have wavelengths that are longer than infrared light in the electromagnetic spectrum.

The wavelength of the radio waves is approximately more than 1 x 10-1 meters.

Therefore, the correct answer option is C. more than 1 x 10-1 meters.
