Question

For constructive interference to take place between two monochromatic light waves of wavelength λ, the path difference should be
(a) $(2n-1)\frac{\lambda}{4}$
(b) $(2n-1)\frac{\lambda}{2}$
(c) nλ
(d) $(2n+1)\frac{\lambda}{4}$

Answer 1

Answer:

For constructive interference to take place between two monochromatic light waves of wavelength λ, the path difference should be (c) nλ.

Explanation:

Wave interference is a phenomenon where two waves superimpose to form a wave of a greater or lower amplitude.

Interference can be comstructive or destructive. When a greater resultant wave is formed, it is called constructive interference and when a resultant wave of lower amplitude is formed, it is destructive interference.

Answer 2

Answer:

Answer:

if the constructive interference is a occur show thebbright spot is form.

according to the double slit experiment we concluded that path difference delta L between extremely is n,¥ where n is refractive index of that medium and lambda is wavelength of light which we use.

this halp you consider the symbol of lambda
