sinθn= (n-1/2) (λ/d) , honestly I really don't understand what this question is askingrpthomps said:What relevant equations do you think you would need?
yesrpthomps said:Do you know what sources are, nodal points and the paths from the sources to the point on the nodal line?
A two point source is a system where two separate sources emit waves of the same frequency and amplitude, creating an interference pattern.
A single point source emits waves in all directions, while a two point source emits waves in specific directions that interfere with each other.
The distance between the two point sources affects the spacing of the interference pattern, with smaller distances creating a wider pattern and larger distances creating a narrower pattern.
The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves. In the case of two point sources, the resulting interference pattern is a combination of the two individual waves.
The relative phase between the two point sources can either enhance or cancel out the intensity of the interference pattern. When the waves are in phase, the interference pattern is enhanced, while when the waves are out of phase, the interference pattern is canceled out.
