What is it called when waves travel through each other and the crests overlap with crests and troughs over lap with troughs?
Standing Waves.
When two waves of the same wavelengths travel such that their crests and also troughs are?
If you have one single sound, it will make a certain type of frequency. Now if the apex of the crest is the exact opposite of the apex of the trough. That single sound will cancel each other out. If you have one single sound, the apex of the crest is exactly the same as the apex of the second sound (at the same frequency) the overall sound will increase.
What factors affect sound waves?
The more dense a material is the faster sound will travel. Sound is dampened when the medium it is traveling through doesn't vibrate well; and when two different sounds cross there will be some places where the sound is amplified and where it is cancelled out, it has to do with the alignment of the crests and troughs, this is a phenomena that occurs with sound and light.
Why do waves of different wavelengths travel at the same speed?
All light travel at the same speed.
What can you say about the speed of the different colors light in air?
I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.

How can you measure the wavelength of a longitude and transverse wave?
Longitidinal waves travel in the form of compressions and rarefractions. the distance beteween 2 consecutive compressions or rarefractions gives the wavelength of the longitudinal wave. transverse wave travels in the form of a sinousidal wave, it has crests and troughs. the distance between 2 consecutive crests and troughs give the wavelength of a longitudinal wave.
Why do waves of different wavelengths travel at the same speed?
All light travel at the same speed.
Do all wavelengths of light travel to the same depth in the ocean?
No. Longer wavelengths travel further. This is true for any media, even air. This is why you see the red light further than the green light.
What happens when two sound waves collide?
Ummmmm, NO. Ignore that. This describes an Echo. Assuming a perfectly smooth surface, the reflected wave travels away from the reflector in accordance with the usual angle of incidence = angle of reflection, diminishing with the square of the distance. Not all the energy is reflected fully. Some is scattered or absorbed by the reflecting surface. If the sound is reflected back and forth in a chaotic overlap the result is reverberation, as in a cathedral or in the ocean. In the sea reverberation gives whale calls that plangent "singing" quality, from what are really only squawks and grunts.
Can all wavelengths of light travel at the same velocity in certain mediums?
Yes, all wavelengths of light have the same velocity in every medium. In fact, all types of electromagentic radiation travel at the same speed in a given medium.
Which color pigment will travel the farthest?
In a perfect vacuum, all wavelengths travel the same distance. In atmosphere, longer wavelengths (red) travel further than shorter wavelengths (blue) due to a phenomenon called Rayleigh scattering. That is why the sky is blue, and the setting sun is red. Similarly, in interstellar space (when we view light from distant stars), shorter wavelengths (blue) do not travel as far as longer wavelengths (red) due to a phenomenon called interstellar extinction. See the Related Links below for Wikipedia articles on Rayleigh scattering and interstellar extinction.
What is difference between normal and anamolous dispersion?
Normal dispersion occurs where shorter wavelengths travel slower than longer wavelengths. Anomalous dispersion occurs when shorter wavelengths travel faster than longer wavelengths.The zero dispersion point for optic fibres is around 1550 nm, which is why most communications systems use this wavelength.
Does the color of a laser affect the velocity of a light wave projected by the laser?
Colors are determined by the wavelengths but all wavelengths travel at the same speed. So no, colors do not affect the velocity of light.
What can you say about the speed of the different colors light in air?
I could say that shorter wavelengths move faster, but that would be wrong. The truth is that all wavelengths/colors travel at the same speed.
