Electromagnetic energy. Broadcasts are usually made using the low part of the radio spectrum up to 1GHz. Above that is microwaves which are not generally used for broadcasts but for things like mobile phones and wireless modems and so forth.

The frequency on the radio dial doesn't tell us the power the station is using to transmit. There may be an AM radio station at any spot on the dial that is transmitting at any power level between, maybe, 10 watts and 50,000 watts. That decision is made when the radio station applies for its license, and the license to operate is granted.

A newspaper is a printed publication that provides news and information in written format, while radio is a broadcast medium that delivers news and entertainment through audio transmissions. Newspapers can be read at any time, while radio broadcasts are heard in real-time.
Radiant energy is made by electromagnetic waves, including visible light, infrared radiation, ultraviolet radiation, and radio waves.
Radio waves are electromagnetic energy, similar to light, but of much longer wave lengths.
Electromagnetic radiation is made of energy. Very small amount of energy for radio waves or large amounts of energy for gamma rays. Visible light is electromagnetic radiation.
Sadly Glenn Miller's career ended before serious commercial television broadcasting began. There are filmed performances but all of his broadcasts were made on radio.
Radio waves are a type of electromagnetic radiation that consists of photons. Photons are the smallest unit of light and carry energy. When radio waves are transmitted, they are made up of photons traveling through space, carrying information and energy.
Locating a radio telescope near a radio station is generally not a good idea due to potential interference from the radio station's broadcasts. Radio telescopes are extremely sensitive to electromagnetic signals, and the noise from a nearby station could disrupt observations and data collection. Ideally, radio telescopes should be placed in remote areas with minimal man-made radio frequency interference to ensure accurate and clear readings of celestial objects.
Earth would appear as a bright source of radio waves to extraterrestrial astronomers due to human-made radio transmissions. These transmissions, including radio broadcasts, satellite communications, and radar signals, create a radio "glow" around Earth that can be detected from great distances in space.
