CUET Physics Waves Optics: Important Points to Remember
There are following important points in this chapter of Waves Optics.
- Polarization is used to check symmetry in crystals and molecules using the phenomenon of optical activity.
- Maxwell had predicted the existence of electromagnetic waves around 1855.
- Central maxima means the maxima formed with zero optical path difference. It may be formed anywhere on the screen.
- Fringes with red light are thicker than those for blue light.
- Ray optics is a limiting case of wave optics.
- Polaroids increase colour contrast in old paintings.
- Polaroids used in three dimensional motion pictures and in optical stress analyses.
- Fresnel’s biprism: It is an equipment which is used for obtaining two coherent.
- The law of conservation of energy holds good in the phenomenon of interference.
- Fringes are neither image nor shadow of slit but locus of a point which moves in such a way that its path difference
from the two sources remains constant. - In YDSE the interference fringes for two coherent point sources are hyperboloids with axis S1S2.
-
If the interference experiment is repeated with bichromatic, Also, used in determination of wavelength of light.
-
Llyod’s single mirror: It is an equipment which is used for obtaining coherent sources of light by reflection from a plane mirror.
-
Llyod’s single mirror: Only half of the interference pattern is available, the central fringe is dark.
-
Llyod’s single mirror: As the ray suffer a phase change of π on account of reflection from a denser medium, therefore, condition for bright and dark fringe is just reversed.
-
Diffraction Grating: It is an optical device which is used for studying the spectra of source of light and is used in the determination of wavelength of light.
-
No interference pattern is detected when two coherent sources are infinitely close to each other, because β ∝ 1/d.
-
If maximum number or maximas of minimas are asked in the question, use the fact that value of sinθ or cosθ can’t be greater than 1. nmax = d/λ and Total maxima = 2nmax + 1.
- Limit of resolution for microscope
- Limit of resolution for telescope
