Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above1 or 3 GHz as microwaves, or include waves of any lower frequency.
Keeping this in view, how are radio waves and ultraviolet waves similar and different?
As wavelengths get shorter, the waves have more energy. X-Rays have smaller wavelengths and therefore more energy than the ultraviolet waves. have the smallest wavelength and the most energy of the waves in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions.
Subsequently, question is, what is the difference between light waves and electromagnetic waves? The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. The shorter the wavelength of the radiation, the higher the energy. The rainbow of colors that we see in visible light represents only a very small portion of the electromagnetic spectrum.
Likewise, people ask, what is the difference between sound waves and radio waves?
Misconception Alert: Sound Waves vs. However, sound and radio waves are completely different phenomena. Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum. Conversely, radio waves are electromagnetic waves, like visible light, infrared, ultraviolet, X-rays, and gamma rays.
Can humans hear electromagnetic waves?
Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched).

What are the uses of electromagnetic waves?
Behaviour and uses of electromagnetic waves Radio waves. Radio waves are used for communication such as television and radio. Microwaves. Microwaves are used for cooking food and for satellite communications. Infrared. Visible light. Ultraviolet radiation.
What is the source of all electromagnetic waves?
Accelerated electrical charges are the source of all EM waves; the energy source is whatever is doing the accelerating.
What color has the longest wavelength?
red
Which color has the highest energy?
Violet
What are the 7 electromagnetic waves in order?
This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Which wave has the highest frequency?
Gamma rays
How are electromagnetic waves produced?
An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light.
Is sound an electromagnetic wave?
Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.
Do radio waves need a medium?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. This proved that radio waves were a form of light!
How far can radio waves travel?
Bands of radio waves Band Frequency range Wavelength range Low Frequency (LF) 30 to 300 kHz 1 m to 10 km Medium Frequency (MF) 300 kHz to 3 MHz 100 m to 1 km High Frequency (HF) 3 to 30 MHz 10 to 100 m Very High Frequency (VHF) 30 to 300 MHz 1 to 10 m
Why is sound not an electromagnetic wave?
There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
How fast do radio waves travel in air?
They transmit radio waves through space to antennas here on the ground.) Sound travels at approximately 1,100 feet per second (766 miles per hour). Radio waves travel at the speed of light, which is approximately 186,000 miles per second.
Do radio waves carry sound?
Radio waves do not transmit just sound; they are *able* to transmit information. If we have sound, for example, which is pressure waves travelling on the air, we can use a microphone to convert the pressure amplitude of the air to electric current on a pair of wires.
How fast do electromagnetic waves travel?
Electromagnetic radiation is a type of energy that is commonly known as light. Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
Can sound waves be reflected?
Sound is reflected from a surface at the same angle at which it strikes the surface. This fact makes it possible to focus sound by means of curved reflecting surfaces in the same way that curved mirrors can be used to focus light.
How fast do sound waves travel?
approximately 332 metres per second
How do you identify electromagnetic waves?
One way to make RF waves visible is with something like a radio telescope. An ordinary (light) telescope collects light and focuses it onto a receptor (CCD, photographic plate, the eye), thus making it possible to see the visible radiation emitted by a distant galaxy.
