Is it true blue light travels slower than red light because it has a shorter wave-length?

Nope, both travel at the same speed, the speed of light. the speed of light, c, is a constant and is approx. 3x10^8 meters per second
Blie light does indeed have a shorter wavelength than red light this results in it have a higher frequency.

Will a wavelength be shorter or longer the slower the object vibrates?
longer
Why do wavelength of light changes when it travels from one medium to another?
It gets shorter due to slower speed. Beware: color depends on frequency, which doesn't change. The frequency of light is defined by its wavelength. When light travels from air into water, there is a phase shift in the electromagnetic ripple, not a frequency shift.
What happens to the frequency as waves slows down?
The frequency of a wave is detemined by the source, and it stays constant, so if the wave enters a medium where the speed is slower, the wavelength becomes shorter.
Why does a glass filled with water distort things?
because light travels slower through water
Light travels slower in a material with greater what?
Light travels slower in a material with greater optical density.
Will a wavelength be shorter or longer the slower the object vibrates?
longer
Why do light waves have a far shorter wavelength than sound waves?
sound waves travel faster slower than light waves In air, sound travels around 300m/s.
Do you shake the end of the rope slowly or rapidly to make the wavelength shorter?
If you shake the rope faster the wavelength decrease. If you shake the rope slower the wavelength increases.

Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
What makes light move slower as it travels?
it moves slower because of sudden movement
Why is a plane seen before its heard?
because sound travels slower
Is Long wavelength visible light have a speed that is slower than short wavelength light which one?
In a vacum all wavelengths of light have the same speed of 3 x 10^8 m/s. However, in a medium like glass or water the speeds of light are different for different wavelengths and the longer wavelength has a higher speed then the shorter wavelength. Although both speeds are slower then their speeds in a vacum.

Light travels slower in a material with greater what?
Light travels slower in a material with greater optical density.
Sound travels slower through gases than through liquids and solids because the molecules in gases are?
sound travels slower through gases as compared to solids and liquids because there is more inter-moleculer space in gas as compared to solids and liquids.
