A direct wave is a radio wave that travels directly through space without getting refracted by the ionosphere. In other words, it travels straight to the receiving antenna without being refracted.

The amplitude of a wave is a direct measure of the energy or intensity of the wave. It represents the maximum displacement of a particle from its equilibrium position as the wave passes through a medium. Larger amplitudes indicate greater energy or intensity of the wave.
wave A
The direct measure of amplitude is the maximum displacement of a wave from its rest position. In simple terms, it represents the height or strength of a wave, such as the height of a water wave or the loudness of a sound wave. Amplitude is usually measured from the peak of the wave to its midpoint.

A baton
Wave A takes a more direct route to the receiving station as it travels through the Earth's interior, while wave B experiences more reflection and refraction as it travels along the Earth's surface.
yes
Direct Current (DC) has an infinite wave length, hence 0 frequency.
Amplitude is the direct measure of energy from a mechanical wave.=Waves are produced by something (a medium) vibrating. The farther the medium moves as it vibrates, the larger the amplitude of the resulting wave. For example, you can increase the amplitude of a wave on a rope by moving your hand up and down a greater distance. To do this you have to use more energy. The energy is transfered to the rope. The greater amplitude is a direct measure of the increased energy.=
