The formula for the speed of light, in vacuum, is
c = 299,792,458 meters/second . where ' c ' is the speed of light.
In any material substance, the speed of light is
c/(the index of refraction for that substance) . Gamma rays, radio waves, and all other members of the electromagnetic spectrum
between those, all have the same speed.
The highest energy photons are described as Gamma. But in terms of the strength, there are more light sources that we encounter everyday of a greater intensity than gamma, as intensity is a measure of the number of photons arriving over an area in a given time. Therefore, visible light and infra-red from the sun are much more intense than the gamma we encounter everyday, as gamma photons are few and far between.

Gamma rays have a much higher frequency than visible light with ultraviolet and x-rays between them.
Violet. Recall VIBGYOR. Violet at the high frequency extreme and Red is at the low frequency extreme

No, visible light has a lower frequency than gamma rays. Gamma rays are the highest frequency of electromagnetic energy. They are above X-rays.
Light ray and gamma ray both travel in a straight line.
In the electromagnetic spectrum, gamma rays at 1021 cycles / sec are the highest, higher values have been detected from astronomical sources though.
Violet for light, gamma rays for entire spectrum.
There is no such thing as the highest frequency. Since photons or electromagnetic travel at the speed of light its frequency correlates to the energy. The highest energy, and thus the highest frequency, is found in cosmic radiation, where a single photon may carry many millions of kiloelectronvolts.
Gamma rays are of higher energy and much much shorter wavelength than visible light.
Cosmic Rays/High Frequency Gamma Rays
Gamma Rays are the highest frequency waves. Lower than that are X-rays then Ultraviolet. Then visible light, infrared, microwave, and radio waves are the lowest frequency. Here is a link which gives more information http://imagine.gsfc.nasa.gov/science/toolbox/emspectrum1.html
The ones we call "gamma rays" do. Their frequency is so high that in the time of one cycle, light travels only a distance similar to the size of an atom.
Gamma rays are electromagnetic waves ... physically and functionally identical to radio, light, heat, etc. ... with the highest observed frequencies (shortest observed wavelengths). In experiments designed to reveal the particle nature of electromagnetic radiation, gamma ray particles (photons) have the highest observed photon energies.
