the wavelength of any reflected or emitted photon or other particle is shortened in the direction of travel.
Viruses. They are smaller than the average wavelength of light and as such are not viewable unless an electron microscope is used.
I assume you are asking in regard to the photoelectric effect. The intensity of the photons can be viewed as the brightness of the light. However, the frequency is the number of wavelengths that pass a certain point in a second. The frequency is also used to determine the energy of the photon (E=hf).
Light is an electromagnetic wave. All electromagnetic waves are a form of energy. This question can be viewed from the quantum theory angle. Light would thus consist of photons with energies proportional to the frequency of the light.
Objects viewed through a light microscope look a lot bigger.
Light waves are an electromagnetic radiation ranging in and wavelength. Only the wavelengths in between about 4,000 (violet) to about 7,700 (red) angstroms can be perceived by the human eye and is called visible light. The wave itself is too fast and too small to be viewed in an isolated manner. However, all light perceived by the Human eye is a light wave.

The Andromeda constellation is best viewed at 21:00 during the month of November.
The Andromeda Galaxy is one of the few galaxies that is observable with the naked eye. Because of this, it cannot be said to be "discovered" as it has obviously been viewed by "man" since the earliest times.
At an apparent magnitude of 3.4, the Andromeda Galaxy is one of the brightest Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution.
In the Northern Hemisphere from June through February

well, right now it is believed that light travels in waves and is made up of massless particles called photons. these waves propagate at a constant speed, 3*10^8 m/s. Nothing can travel faster than this speed and nothing can travel the speed of light if it is not massless (so sorry, no hyperspace travel yet) while light always travels at the same speed, the frequency and wavelength of these propagating waves are not always the same. In the visible spectrum, the highest frequency waves are viewed as purple and the lowest frequency waves are red. The faster the frequency, the more energetic the wave. the frequency, wavelength, and speed of light are related to each other by this equation: speed of light=wavelength*frequency when dealing with the electromagnetic spectrum it is often easier to refer to light as electromagnetic radiation, especially when dealing with very high and very low frequencies that result in infrared, ultraviolet, radio, x-ray, etc. there is a lot of information out there about light, I'm just scratching the surface :-)
