Gotham lighting

Light up parking lots, pathways and roadways with RDA Lighting’s new AL3-LED Fixtures! With a lumen package of 38,500 and 46,400 lumens, these fixtures are the ideal replacement for 1000W HID fixtures. replacement for 1000W HID fixtures.

Distinguish between unpolarised light and linearly polarised light. How does one get linearly polarised light with the help of a polaroid ?

Pal lighting

Show using a proper diagram how unpolarised light can be linearly polarised by reflection from a transparent glass surface.

Mark architectural lighting

Deliver the perfect amount of light while eliminating hot spots and glare. All AL-LED fixtures available in T2, T3, T4, T5. Photometrics shown as mounted on a 30ft pole.

(a) Distinguish between unpolarised light and linearly polarised light. How does one get linearly polarised light with the hel of a polaroid ? (b) A narrow beam of unpolarised light of intensity I0 is incident on a polaroid P1. The light transmitted by it is then incident on a second polaroid P2 with its pass axis making angle of 60â relative to the pass axis of P1. find the intensity of the light transmitted by P2.

Indy lighting

(a) How does one demonstrate, using a suitable diagram, that unpolarised light when passed through a Polaroid gets polarised? (b) A beam of unpolarised light is incident a glass-air interface. Show using a suitable ray diagram, that light reflected from the interface is totally polarised, when Î¼=taniB, when Î¼ is the refractive index of glass with respect to air and iB, is the Brewster's angle.

A : The unpolarised light and polarised light can be distinguished from each other by using polaroid. R : A polaroid is capable of producing plane polarised beams of light.

The AL-LED Series delivers superior lighting performance while significantly reducing energy consumption and maintenance costs.

Explain the following giving reason for each: (a) How does a polaroid work to produce a linearly polarised light from an unpolarised beam of light ? (b) Why is it that light waves can be polarised but sound waves cannot be ? (c) Why are sun goggles made of polaroids preferred over those using coloured glasses ?
