Want this question answered?
The speed is, and, as a direct consequence, the wavelength.
Velocity (speed and direction) Wavelength (frequency)
it changes in velocity
the speed and wavelength increase but the frequency stays the same
When light passes through a second medium with different refractive index as the first medium, its velocity will decrease or increase depending on its wavelength and the difference in refractive index of the two media. This causes the 'bending' of light as each of its components try to travel through the second medium at different velocities.

No, the amplitude of a wave does not affect the wavelength or wave speed. The wavelength is determined by the frequency of the wave, while the wave speed is determined by the medium through which the wave is traveling. Amplitude simply represents the maximum displacement of particles in the wave.
The answer depends on what on earth you mean by the "dirtier" of a wave.

The wavelength gets longer.
When light passes through a second medium with different refractive index as the first medium, its velocity will decrease or increase depending on its wavelength and the difference in refractive index of the two media. This causes the 'bending' of light as each of its components try to travel through the second medium at different velocities.
The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.
yes
Wavelength is halved.
Assuming an electromechanical wave not much. The speed of the wave depends on the medium that the wave is passing through. In a vacuum it is the speed of light, through something else a lesser speed. The wavelength stays the same and the frequency stays the same.
