Solved problem: Missing order spectra in Fraunhofer diffraction

Solved problem: Missing order spectra in Fraunhofer diffraction

Que: In double slit diffraction what should be the ratio of a & b such that, the central diffraction maximum contains exactly seven interference fringes. what must be the ratio if the central maximum contains exactly five fringes? ‘a’ is slit width and ‘b’ is the separation between the two slits.

Sol.  

case when central diffraction maximum contains exactly seven interference fringes

How can you determine the direction of the polarizing axis of a single polarizer?

How can you determine the direction of the polarizing axis of a single polarizer?

Q. How can you determine the direction of the polarizing axis of a single polarizer?

Ans: If you are given only linear polariser, in order to find its polarising axis one can make use of Brewster’s law. At Brewster’s angle, reflected light from from a reflecting surface is completely polarized with plane of polarisation parallel to reflecting surface (green dots). At angle other than Brewster’s…

Discussion Questions in Optics

Q. Light requires about 8 minutes to travel from the sun to the earth. Is it delayed appreciably by the earth’s atmosphere? Explain.

Ans: Distance between earth and sun is about 147.83 million km, where as earth's atmospheric thickness is about 480 km which is negligible to distance covered in atmosphere. Moreover refractive index of air is 1.0003 which further approaches 1 with increase in…

20 project ideas in optics

Optics is the most visually appealing branch of Physics. Visuals from optics can make any student fall in love with the subject. But when it comes to hands on experiment it can be little tricky. As here dimensions are very important. With change in size of aperture one can go from Fresnel to Faunhoffer class of diffraction. Or from shadow to diffraction pattern. With the knowledge of sound theory…

Easy DIY diffraction pattern from circular aperture

Easy DIY diffraction pattern from circular aperture

Diffraction is one of the easy phenomenon to demonstrate in order to explain the wave nature of light. This can be with the help of laser, fine needle (to pierce hole), aluminum foil , glass slide, stand and screen.

Diffraction pattern formed by circular aperture

pierce hole in Aluminum foil keeping in mind less is more (i. e. smaller is the aperture greater will be the diffraction).

Stick foil…
