Why don't we see interference of light from two light sources such as two candles? 2 reasons are required.
Thanks

Light Interference: Why Don't We See 2 Sources? 2 Reasons

SUMMARY
The discussion centers on the phenomenon of light interference and why it is not observed with two light sources, specifically two candles. Two primary reasons are identified: the wavelength of the light and the phase of the light waves. The wavelength must meet specific conditions for interference to occur, while the phase relationship between the waves is crucial for observable interference patterns. These factors are essential in understanding the limitations of light interference in practical scenarios.
PREREQUISITES- Understanding of light wave properties, including wavelength and phase.
- Basic knowledge of interference patterns in physics.
- Familiarity with the concept of coherent light sources.
- Knowledge of fundamental optics principles.
- Research the conditions for light interference in coherent light sources.
- Study the role of wavelength in wave interference phenomena.
- Explore the concept of phase difference in wave mechanics.
- Investigate practical applications of interference in optics, such as in lasers.
Students of physics, educators teaching optics, and anyone interested in the principles of light behavior and interference patterns.

I was all set to answer till you added "2 reasons are required"... it makes this sound suspiciously like a homework problem.

since this is a homework problem, i can't give you the answer..(you said 2 reasons are required) 
but i'll give you some hints lead to the answer
1. wavelength... in order for a interference exist... what is the restriction on the wavelength?
2. the phase of the light wave...
