Question

In an interference experiment a transparent glass plate with refractive index 'n' and thickness 't' is introduced between the slit and the screen, the optical path shifts by​

Answer 1

Answer:

$answer$

For minimum thickness, (n−1)t=λ

t=

(n−1)

λ

=

(1.5−1)

λ

=2λ

Answer 2

The slit and the screen, the optical path shifts by​ 2λ

Explanation:

• The net impact of the combination of  2 or more wave trains transferring on intersecting or coincident paths.
• The impact is that of the addition of the amplitudes of the individual waves at every factor suffering from more than one wave.
• This means that the 4 types of interference all promote diversification, albeit to exclusive extents.
• Foraging, metabolic, and survival interference are much more likely to allow diversification than reproductive interference.

For minimum thickness,

(n−1)t = λ

(n−1)λ = t

= (1.5−1)λ

= 2λ
