To solve this problem we will apply the concepts given by the principles of superposition, specifically those described by Bragg's law in constructive interference.
Mathematically this relationship is given as

Where,
d = Distance between slits
= Wavelength
n = Any integer which represent the number of repetition of the spectrum

Calculating the value for n, we have
n = 1

n=2

n =3

Therefore the intensity of light be maximum for angles 23.3° and 52.28°
Answer:
Explanation:
the object will not move as the force exerted is not sufficient enough to overcome its force of friction
Answer:
66w
Explanation:
p=w/t
p=660/10
p=66
prolly a bad explanation but hope it helps...
