Answer 1

1. Every oscillator in a wave creates spherical wavelets that propagate outwards
2. The wave front created by these oscillators is due to combined interference of the wavelets

Question 2

Distance to a maximum

Answer 2

Xm : (m x (wavelength) x L)/d

Question 3

Distance between slits

Answer 3

d : m x (wavelength) x sin(angle)
