Radio waves have a low frequency and a long wavelength. (A. low; long)

Explanation:

Electromagnetic waves are periodic oscillations of the the electric and the magnetic field in a plane perpendicular to the direction of motion the wave.

All electromagnetic waves travel in a vacuum at the same speed, which is known as the speed of light:

$c=3.0\cdot 10^8 m/s$

Electromagnetic waves are also divided into 7 different types, according to their wavelength and frequency. From shortest to longest wavelength (and therefore, from highest to lowest frequency), we have:

Gamma rays

X rays

Ultraviolet

Visible light

Infrared radiation

Microwaves

Radio waves

As we can see from the list, radio waves are the waves with lowest frequency and longest wavelength. They are used in telecommunications, satellite communications, and in general in long-distance transmission of signals. So, the correct answer is

Radio waves have a low frequency and a long wavelength.

Why does the modern atomic theory used today represent the best explanation scientists have to offer?

LenaWriter [7]

Answer:

D: Scientists have not been successful in disproving the atomic theory.

Explanation:

This theory has had great implications in the understanding of nature at the microscopic level, from the first atomic model to the quantum model of the atom. All modern physics, chemistry and biochemistry are based on the theory that matter is composed of atoms of different elements. It has not been possible to disprove this theory or replace it with a better one.

Precipitation tends to be _______ on the _______ side of a mountain because water vapor _______ as it rises there.

Lera25 [3.4K]

Answer:

Higher, Windward side, Condenses

Explanation:

The Windward side refers to that side of a mountain that faces the direction from which the wind is blowing. In this direction, the moisture containing hot air blowing from a distant place moves upward and strikes the mountain at a greater height, where the air mass is thin and the temperature is relatively cold. As the temperature and pressure decrease with altitude, the hot uprising air cools and gradually condenses. This results in the occurrence of high precipitation over this region i.e. the windward side of the mountain.

Therefore, the precipitation is always higher on the windward side of a mountain as the hot air undergoes condensation at greater height as it rises upward.
