How come we don't see light interference from two light sources?
ex. two candles

Light interference is a phenomenon where two or more light waves overlap and interact with each other, resulting in either constructive or destructive interference. This can affect the overall intensity and color of the light.
The two main types of light interference are constructive interference, where the waves combine to form a larger amplitude, and destructive interference, where the waves cancel each other out.
Light interference can affect the appearance of objects by changing their color or brightness. For example, when white light is shone on a thin film of oil, the different wavelengths of light interfere with each other, resulting in a colorful pattern.
Coherent light interference occurs when the interfering waves have a constant phase relationship, such as in laser light. Incoherent light interference occurs when the interfering waves have random phase relationships, such as in sunlight.
Light interference is used in various technologies such as anti-reflective coatings on glasses and camera lenses, optical filters, and holograms. It is also used in research to study the properties of light and in medical imaging techniques like optical coherence tomography.
