Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) – (II), (B) – (III), (C) – (I), (D) – (IV)
Each wave phenomenon of light is linked to one property of waves.
(A) Transverse nature of light — this matches (II) Polarisation. Only transverse waves have vibrations perpendicular to the direction of travel that a polaroid can restrict to one plane, so polarisation proves that light is transverse.
(B) Superposition of two or more waves — this matches (III) Interference. When coherent waves overlap, their displacements add, giving bright and dark fringes.
(C) Bending /spreading of light waves — this matches (I) Diffraction. Light spreads into the geometrical shadow when it passes an obstacle or an aperture comparable in size to its wavelength.
(D) White light splits into various color components — this matches (IV) Dispersion. The refractive index of glass depends on wavelength, so each colour bends by a different amount in a prism.
NCERT (2026-27):
Introduction – “… In Sections 10.4 and 10.5, we will discuss the phenomenon of interference which is based on the principle of superposition. … Finally in Section 10.7 we will discuss the phenomenon of polarisation which is based on the fact that the light waves are transverse electromagnetic waves.”
Diffraction – “If we look clearly at the shadow cast by an opaque object, close to the region of geometrical shadow, there are alternate dark and bright regions just like in interference. This happens due to the phenomenon of diffraction.”
Summary – “… 7. Dispersion is the splitting of light into its constituent colour.”
