Yes, radio wave can reflect off of surfaces. Dish antennas use this property to focus the radio waves to a single point and produce very high directivity.
Yes.
It is the ionosphere, a general region that includes all of the thermosphere and parts of the two bordering layers. In this region, between 60 and 1000 kilometers above the Earth, ionized particles refract and reflect radio waves back toward the ground. This enables radio transmissions that are normally "line of sight" only to reach over the horizon for hundreds or thousands of miles. This includes broadcast radio (HF) and shortwave bands.
The ionosphere - specifically the e-layer
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
An F-16 isn't stealthy. "Stealth" aircraft are designed to not reflect radar signals back to the transmitter. Since almost all metallic materials will reflect radio waves, they can only be "stealthy" by reflecting the radio waves someplace else other than "back to the transmitter". Stealth aircraft avoid vertical fins and flat surfaces; the rounded surfaces and angled fins are designed to reflect the radar waves up into space, or down to the ground.
The ozone layer contains electrical charged particles that reflects radio waves
Some surfaces reflect sound well, others don't.
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat.

The ionosphere has nothing to do with radioactivity, and there is nothing in nature that is called a "radio active wave."Because the ionosphere contains electrical charges, it is able to reflect radio waves.
Radio waves will be reflected by any surface where the electromagnetic properties of the space change. e.g. moving from free space into solid material.

Echoes can be heard in environments with hard and flat surfaces that reflect sound waves, such as mountains, canyons, buildings, or empty rooms. When sound waves bounce off these surfaces and return to the listener, an echo is produced.
Yes all metal foils reflect heat (and other electromagnetic radiation: light, radio waves, etc.).

The term skywave is used to refer to the reflect radio waves from the ionosphere. ?æSkywave is used most frequently in shortwave radio broadcasts.
light and smooth surfaces reflect heat energy
