What does it mean for something to have wavelike properties?
Waves are characterized by wavelength, frequency, and speed. Wavelength is the distance between two consecutive peaks or troughs in a wave. The frequency is defined as the number of waves (cycles) per second that pass a given space. Since all types of electromagnetic radiation travel at the speed of light, short-wavelength radiation must have a high frequency and long-wavelength radiation must have a low frequency.
How do electromagnetic radiations differ?
Electromagnetic radiation is concerned with the movement of photons (individual, discrete 'packets' of light energy.) The frequency of electromagnetic radiation is directly proportional to its energy and inversely proportional to it's wavelength. Thus, a higher frequency will mean that the photons have a shorter wavelength and have more energy.Different frequencies, and therefore energies, of electromagnetic radiation will give it different properties. Because of this, the frequencies of electromagnetic radiation are divided into a spectrum based on the different properties of electromagnetic radiation of different frequencies. This spectrum goes from radio waves at the very low end to gamma rays at the other end.See the link at the bottom for a diagram of the Electromagnetic Spectrum.However, in the below image the word 'heat' is wrong. Between Infra-red and Radio waves are microwaves.Nuclear radiation is normally concerned with any form of radiation emitted as a result of radioactive decay, in which a large, unstable nucleus of an atom breaks down to form a more stable one.There are three types of nuclear radiation: alpha, beta, and gamma. Alpha decay is when an unstable nucleus emits an alpha particle which is composed of two protons and two neutrons; i.e. it is effectively a helium nucleus. Beta decay is when an unstable nucleus emits a beta particle (an electron), and gamma emission is when an unstable nucleus emits high energy electromagnetic radiation called gamma rays.
Does electromagnetic radiation include only visible light waves?
Not exactly. Actually, no. Photons are chunks of electromagnetic waves. As such, they do not produce EM waves, they ARE those waves. A photon inter-acting with some other particle could result in other photons -- ie, a different kind of EM wave -- being created.
What do you mean of speed of electromagnetic radiation?
The speed of electromagnetic radiation can be found using the refractive index of a material. The refractive index n is equal to the ratio of the speed of light in a vacuum to the speed of light in the substance. Electromagnetic waves propagate at different speeds in different materials.
When calcualting the speed of sound do you multiply or divide the distance by the frequency?
When calculating the speed of sound do you multiply or divide the distance by the frequency? If you mean the formula for the speed of sound c then the wavelength lamda is multiplied by the frequency f. c = lambda x f f = c / lambda lambda = c / f
What does frequency of light mean?
Light is known to be electromagnetic radiation, and as such it is of waveform nature. As a waveform, it has wavelength and its counterpart frequency.

What part of the electromagnetic spectrum has the greatest frequency?
If by greatest frequency you mean highest frequency, we know that the upper end of the electromagnetic spectrum has the greatest frequency. This is the home to the gamma rays. They have the highest frequency, shortest wavelength, and the greatest energy.
What electromagnetic radiation is the least energetic?
Perhaps you mean one of these, I can't tell:Alpha particle radiation: least penetrating ionizing radiation, 100% shielding provided by one sheet of paper.ELF radio: lowest energy radio waves (~0.01Hz), travels long distances and through water. U.S. Navy experimented with it for communicating with Submarines.Red light: Lowest frequency of visible light.Violet light: Shortest wavelength of visible light.Very High Energy Gamma radiation: Shortest wavelength of any known radiation.Anyway, least in what way?
What happens when solar radiation leaves the sun?
Assuming you mean electromagnetic radiation, once it leaves the Sun it will go outwards at the speed of light (300,000 kilometers per second).
What does lighting mean?
verb - to illuminate, or to set afire adjective - not heavy, or of lower caloric content adjective - of a color that is less dark noun - illumination, or a source of illumination noun (physics) - radiation : any frequency of electromagnetic radiation within the visible range for human beings. This constitutes a comparatively small range of possible electromagnetic energies. -- Briefly, light or light(s) means: 1) Electromagnetic radiation of a visible frequency or wavelength 2) A source of illumination 3) A source of fire or to set fire 4) A comparative shade of color or hue 5) Laundry that is not dark in color

How do you find wave length and speed when none is given but frequency is given?
Well, do you know what kind of wave they're talking about ? I mean, is it sound ? Is it electromagnetic, like light or radio ? If it's one of those, then you know the speed, and with speed and frequency, you can calculate wavelength. If it's just a question on a piece of paper that says "There's a wave and it has this frequency, what is it's speed ?", then no answer is possible ... you have one measly piece of information and everything else is unknown.
What did the flag mean to the American colonists during the revolutionary war?
The distance between the crest of one wave of electromagnetic radiation and the crest of the next one is its frequency/ when a star runs out of fuel, it caanoot become a neutron star.
Is there raideaction in a mri?
If you mean "radiation" then the answer is yes. Electromagnetic radiation in the radiofrequency spectrum. Note that this differs from x rays in that it is not damaging to the tissues.
When the magnitude of kc is very large it indicate?
IF by "kc" you mean the outdated term kilocycles [a measurement of frequency, usually used in measuring electromagnetic radiation (radio)] then the larger (greater) the magnitude, the higher the frequency and the shorter the wavelength. This is basic physics... Your description indicates a poor mastery of technical English.
