They must arrive 180 degrees out of phase. (Waves must be of the same frequency.) In a situation where two identical waves (amplitude and frequency) arrive 180 degrees out of phase, the crests meet the troughs and the troughs meet the crests. The waves effectively "cancel each other out" here, or, as a mechanic might say, the vector sums of the waves total zero. If the waves are not equal in amplitude (but are in frequency), they will at least sum to a minimum energy. Put two speakers 10 to 20 feet apart and point them toward each other. Hook everything up "normally" and walk between the speakers. Then reverse the speakers wires to one speaker. (No, it won't hurt the speakers or the audio system.) Walk between them again. Biiiiiiig difference. Note that this experiment is a 3-dimentional test. Study a bit on the 2-dimentional problem before moving to 3-D. (It's just that this experiment is fun! It makes the phenomenon so real to the observer.) This a problem in what is sometimes called two-point source interference. Use the link to visit a site where drawings are posted. A picture is probably worth a thousand words in this case.
Two light waves need to have the same frequency, be coherent (in phase with each other), and overlap in space to form an interference pattern of bright lines and dark areas. This occurs when waves meet at specific points where they reinforce or cancel each other out due to their phase relationship.
You mean conditions for getting sustained interference pattern with clarity. 1. Sources have to be monochromatic and coherent 2. Two sources have to be so close as far as possible 3. The screen is to be kept at far distance
An example of interference of light is when two light waves meet and overlap, leading to either reinforcement (constructive interference) or cancellation (destructive interference) of the waves. This can result in the creation of patterns, such as in the famous double-slit experiment where interference of light waves produces an interference pattern on a screen.
The combining of light is called interference. Interference occurs when two or more light waves overlap, leading to either reinforcement (constructive interference) or cancellation (destructive interference) of the waves.
Interference is a phenomenon demonstrated by light but not by sound waves. Interference occurs when two or more waves overlap in space and combine to produce a resultant wave. Light waves can exhibit interference patterns such as in Young's double-slit experiment, while sound waves do not exhibit similar interference effects.

Interference in light waves occurs when two or more waves overlap and combine. Constructive interference happens when the waves align to increase the amplitude, resulting in a brighter light. Destructive interference occurs when the waves are out of phase and cancel each other out, leading to a darker area called a node.
Interference and diffraction of light waves can be explained by the wave nature of light. When light waves interact with each other or with obstacles, they can either reinforce each other (constructive interference) or cancel each other out (destructive interference). Diffraction occurs when light waves bend around obstacles or pass through small openings, causing them to spread out and create interference patterns. These phenomena demonstrate that light behaves as a wave, exhibiting properties such as interference and diffraction.
Interference effects are not easily observed in light waves because they require precise conditions such as coherent sources and a controlled environment without disturbances. Any variation in the sources or the medium can disrupt the interference pattern, making it difficult to observe in everyday situations. Additionally, the wavelength of light is very small, making the interference effects more challenging to detect without specialized equipment.
Identical light waves in phase are called coherent light waves. Coherent waves have a constant phase difference between them, which allows for constructive interference and the formation of interference patterns.
When two light waves interfere, they can either reinforce each other (constructive interference) or cancel each other out (destructive interference). This affects the overall pattern of light waves by creating areas of bright and dark spots, known as interference patterns.
Interference and diffraction are phenomena that occur when light waves interact with each other or with obstacles. Interference happens when two or more light waves combine to either strengthen or weaken each other, creating patterns of light and dark areas. Diffraction occurs when light waves bend around obstacles, causing them to spread out and create patterns of light and dark areas. These effects can alter the behavior of light waves, leading to phenomena such as the formation of interference patterns or the spreading out of light waves around edges.
Interference in light is recognized by observing the patterns created when two or more light waves interact. This can manifest as alternating bright and dark fringes in a pattern known as interference fringes. The interference occurs when the peaks and troughs of the light waves either reinforce (constructive interference) or cancel out (destructive interference) each other.
