It means that all the parts of light are in phase - the crest of the waves for one photon coincide with the crests of the waves for another one.

What is coherent light?
Coherent light is when all the photons have the same wavelength and are in the same phase.
How do you produce two coherent sources of light?
two coherent light sources are produced by splitting a single light source
What are the coherent light source?
The Sun
A laser produces light that?
is coherent
What is monochromatic coherent light?
a.k.a. "laser"
Is poly chromatic light can be coherent?
Coherent light (like a laser) is a single frequency. Polychromatic light is, by definiation, multiple frequencies and cannot be coherent.
What is a device that produce coherent light?
The name of the device that produces coherent light is LASER.

Is it true or wrong that if the light rays are not coherent you would not be able to see interference?
To generate an interference pattern the light needs to be coherent.
Light of only one wavelength that travels with its crest and troughs aligned?
That's monochromatic, coherent light. A well known source of such light is a laser.
Can a laser be made from a light bulb?
No. Laser light is coherent. Light bulb light is not.
What is monochromatic coherent light?
a.k.a. "laser"
What are coherent sources and conditions for it?
Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
