Answer:
Δx=dcosθ=nλ (for maxima)
cosθ=nλd⇒cosθ=n2
For maxima, n=1
θ=60∘
Explanation:
In physics, wave sources are coherent if their frequency and waveform are same. Coherence is a super assets of waves that allows stationary (i.e. temporally or spatially consistent) interference. It incorporates several distinct standards, which might be proscribing cases that never quite arise in truth but permit an understanding of the physics of waves, and has come to be a very critical concept in quantum physics. extra commonly, coherence describes all properties of the correlation among physical portions of a single wave, or among numerous waves or wave packets.
Interference is the addition, within the mathematical experience, of wave features. A unmarried wave can intrude with itself, but that is nevertheless an addition of waves (see young's slits test). optimistic or unfavorable interference are restrict cases, and two waves usually intervene, even supposing the end result of the addition is complicated or not notable. when interfering, waves can add together to create a wave of greater amplitude than either one (positive interference) or subtract from every other to create a wave of lesser amplitude than both one (unfavorable interference), depending on their relative section. two waves are stated to be coherent if they have a consistent relative section. the quantity of coherence can without problems be measured with the aid of the interference visibility, which appears at the scale of the interference fringes relative to the enter waves (because the segment offset is numerous); a precise mathematical definition of the degree of coherence is given by way of correlation features.

Assertion: For identical coherent waves, the maximum intensity is four times the intensity due to each wave. Reason: Intensity is proportional to the square of amplitude.
