E = hv where that "v" is actually supposed to be the Greek letter nu, standing for frequency. So just convert the wavelength to frequency and multiply by Planck's constant and you'll have your answer.
here, energy E = hf where h = plank const, f = c*wavelenght c =3*10^8m/s h = 6.626*10^-34 then simplyfying got ans....

gamma rays
The kinds of electromagnetic radiation differ in the length of their waves, so the electromagnetic waves are absorbed, scattered, or reflected by the atmosphere and Earth's surface
Radio Waves have the longest wavelength of any EM radiation, so they usually have the least energy.

I believe you are actually asking the wrong question, if you are referring to a ray of light. From the viewpoint of classical physics (which designates radiation as a wave), there is no comment on the length. Given that radiation travels at the speed of light (c =~ 3*10^8 m/s) the length of a ray could be the duration of the source (in seconds) times the speed of light. However, in quantum mechanics, radiation is composed of discrete particles, called photons. Photons are massless, and there is no comment on the length, or geometry of a photon.
You have gamma rays, x-rays, ultraviolet rays, light rays, infra red rays, microwaves and radio waves in increasing order of wave length and and decreasing order of frequencies. Out of which radio waves have lowest energy. Longer the wave length, lower is the energy.
Infrared radiation is a form of energy with wavelengths that are longer than red light. You can look up pictures of a Light Waves Spectrum to find out the length of red light. infrared radiation is invisible, but can be felt as heat.
The pure state of a quantum system is usually denoted by the vector ket with the unit length.

Photons, because higher frequencies have more energy higher frequency light is more energetic. Flames are simply excited electron releasing energy in the form of light. Energy progresses from red to violet in terms of visible light because violet has shorter wave length and hence higher frequencies. Also note that in the science of quantum mechanics, all forms of matter, energy, space and time are divided into small packages called quanta. The whole point is that physical quantities, unlike mathematical quantities, are not infinitely subdivisible. There is a limit to how small something can be, and that limit is a quantum. EDIT: A nice answer, although it has nothing to do with the question. A quanta is the smallest unit of energy.

Divide the speed of light (300 x 106 meter/second) by the frequency. The answer will be in meters.
X-RAYIt is produced when accelerated catode rays fall on the atom of higer atomic number. Due to collision its energy is increased and electron excited. It goes to higher energy level by obsorbing energy.It emits certain type of radiation of different wave length. Its wave length is very small therefore it has high energy.
