Two polaroids P1 and P2 are placed with their pass axes perpendicular to each other. An unpolarised light of intensity Io is incident on P1. A third polaroid P3 is kept in between P1 and P2 such that its pass axis makes an angle of 45° with that of P1. Determine the intensity of light transmitted through P1, P2 and P3

Depth of field is determined by three factors – aperture size, distance from the lens, and the focal length of the lens. Let's look at how each one works.

The reflected light is found to be plane polarised when an unpolarized light falls on a denser medium at 60° with the normal. Find the angle of refraction and critical angle of incidence for total internal reflection in the denser to rarer medium reflection.

Find an expression for intensity of transmitted light when a polaroid sheet is rotated between two crossed polaroids. In which position of the polaroid sheet will the transmitted intensity be maximum?

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

Light-emitting diodes are semiconductors that convert electricity to light. Although you might think of this type of light as new technology, an engineer at General Electric invented the first one in 1962. The original lights were red, followed by yellow, green, and blue. White lights debuted in the 1990s. While colored lights had been used only in things such as clocks and traffic lights, white LEDs gained widespread use in photography and video.

The refractive indices of glass and water w.r.t. air are 3/2 and 4/3 respectively. Determine the refractive index of glass w.r.t. water.

With the help of neat diagram, explain how non-polar dielectric material is polarised in external electric field of increasing intensity. Define polarisation in dielectrics.

LED lights can be your best choice for lighting your studio. They're inexpensive, don't put out the amount of heat that other studio lights do, and come in a variety of configurations. Their illumination is similar to natural light, and has the versatile color balance. When tungsten lights or fluorescent lights don't fit the situation or the budget, consider LEDs.

Unpolarised light is incident on a polaroid. How would the intensity of transmitted light change when the polaroid is rotated?

A ray of light passes from a vacuum to a medium of refractive index (μ). The angle ofincidence is found to be twice the angle of refraction. The angle of incidence is _______.

LEDs offer a choice of styles. You can use a small panel on a light stand to highlight a face in a portrait, while larger LED panel lights would provide soft light for a full body image. Single LED lights are too small to light a photo, but used as accents, they could add interest to a picture.

Energy-efficient LEDs are cooler than traditional studio lights. You can place them close to a subject without causing discomfort. You can also use them in spaces that are too small to be safe for lights that run hot. These characteristics make LEDs useful for portrait photography. For drama in your portrait, put a light on either side of your subject. This results in an all-over highlight. If your design calls for only one highlight, place a light on just one side. Use colored LEDs to alter the mood in your photograph. Since LEDs are continuous light, you can move around as you compose a shot, or use a remote camera control. If you're a videographer, this constant light is suitable for action shots.

Why Use LEDs for Photos?LEDs can provide continuous light, as opposed to the off-and-on flashes of strobe lighting. For photography and videography, choose continuous light when you need to mimic certain types of illumination sources, or you need to see the result of composition before shooting an image. LEDs convert 90 percent of their energy into light. This makes them not only a cost-effective choice, but environmentally friendly as well. Like the tungsten light kits that are still popular in videography, LEDs come grouped with accessories in LED lighting kits. If you need convenience, some kits are built around battery LED lights.LEDs offer a choice of styles.

Show, using a simple polaroid, that light waves are transverse in nature. Intensity of light coming out of a polaroid does not change irrespective of the orientation of the pass axis of the polaroid. Explain why.

An unpolarized light beam is incident on the polarizer of a polarization experiment and the intensity of light beam emerging from the analyzer is measured as 100 Lumens. Now, if the analyzer is rotated around the horizontal axis (direction of light) by 30° in clockwise direction, the intensity of emerging light will be ______ Lumens.
