Question

3. Two E&M sources, A and B, are separated by a distance of 2.0 m. The sources emit a 1 dimensional wave of wavelength 0.25 m that have a phase difference of π rad. What type of interference will there be at a point 0.5 m to the right of source A?

Answer 1

Δab = 9λ/2 (destructive interference)

Step-by-step explanation:

λ=0.25 m

Δa=2λ

Δb=6λ

Δab=4λ+λ/2

Δab=9λ/2 (destructive interference)
