why is there no Dispersion of white light in the rectangular slab

nnagababu726pb8ss4: because there is no TOTAL INTERNAL REFLECTION (T.I.R)

Answered by dineshmercury5

The rectangular slab doesn't act as prism or water molecules which disperses light due to it's higher refractive index

Aequanimitas: if i am correct i hope glasses have same refractive index

Manbir21: yeah

Aequanimitas: then how come u can say prism and rectangular slab has varying indices

Manbir21: prism has inclined surface but slab does not provide such consequences thus it may be reason

Aequanimitas: i think the answer is that the prism has a peculiar shape which helps in the dispersion

Aequanimitas: correct me if i am wrong

Manbir21: i think you are correct

Aequanimitas: yeah thanks. bye bro prepare well for ur exams

Manbir21: welcome .. same to u if you are in same grade

CONSIDER A GLASS SLAB AS TWO TRIALNGLES

THE TWO TRIANGLES MAKE TWO RIGHT ANGLE PRISM

HENCE NEWTON S LAW OF DISPERSION OF LIGHT IN TWO PRISMS THE SCATTERING OF LIGHT BY PRISM IS REVERSED OR NULLIFIED BY THE SECOND PRISM

HENCE NO SPLITTING OF LIGHT TAKES PLACE.

Manbir21: bro is its about inclined surface
