No.
The velocity of visible light waves is the same as the velocity of radio waves in a vacuum, both traveling at the speed of light (approximately 299,792 kilometers per second).
Electromagnetic waves (same as visible light).
No, infrared waves have longer wavelengths than visible light waves. Infrared waves have wavelengths ranging from about 700 nanometers to 1 millimeter, while visible light waves have wavelengths ranging from about 380 to 750 nanometers.
Visible light has higher frequency than that of infra red radiations. The order of electro magnetic waves in the increasing order of frequency are as follows: Radio waves, micro waves, infra red, ROY G BIV (visible region), ultraviolet, X-ray and gamma ray.
All of them are electromagnetic waves.
No, radio waves and visible light waves both travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. The speed of light is constant, regardless of the wavelength of the electromagnetic radiation.
Oh but it is. When they encounter sharp edges, light and sound behave exactly the same ... in terms of their wavelengths.
Light "rays" are both waves and particles, that is the nature of light. Thus Micro Waves is the name for a type of light that is in essence just the same as visible light, radio waves, heat and X rays.
No, visible light and ultraviolet light are not the same. Visible light is the range of electromagnetic radiation that can be detected by the human eye, while ultraviolet light has a shorter wavelength and higher frequency than visible light, making it invisible to the human eye.
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.
They never do.
No, radiant energy and sound waves are not the same. Radiant energy refers to electromagnetic radiation such as light and heat, while sound waves are mechanical waves that require a medium, such as air or water, to propagate.
