The same.
"High" and "low" only have meaning when they're compared to something. Visible light has high energy compared to radio waves, and low energy compared to X-rays.
Infrared waves are shorter than radio waves and longer than visible light waves.
The longest radio wave used for communication is around 3 millimeters long. The shortest visible wavelength of light is around 0.0004 millimeters long.
Radio, radio is around 10^3 m and visible light is around .5 *10^-6 m.
Infrared waves are shorter than radio waves and longer than visible light waves.
"High" and "low" only have meaning when they're compared to something. Visible light has high energy compared to radio waves, and low energy compared to X-rays.
Both are electromagnetic waves travelling at a speed about 300,000 km in one second in free space or in air medium. But radio waves have longer wavelength compared to that of light waves.
X-rays, gamma rays, radio waves, and visible light are forms of electromagnetic radiation. Gamma rays are highest in energy compared to other electromagnetic radiations. Radio waves are least in energy in the whole electromagnetic spectrum.
Infrared waves are shorter than radio waves and longer than visible light waves.
Radio waves have a longer wavelength than visible light.
No.
It is not necessary to do so, as atmosphere doesn't distort radio signals as much as visible light.
astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
