A photographer using a camera photographs a rare bird roosting on a high branch of a tree at an angle of elevation of 32°35′. The distance between the camera lens and the bird is 350 ft. In order to get a clear picture, the photographer moves closer to the base of the ..

From the top of a tower of height h meters the angle of depression of a red car is φ ° and the angle of depression of a blue car which is on the opposite side of the tower is θ °. If the distance between the foot of the tower and the red car is y mete..

A low-dose x-ray source moves in an arc (360 o ) around a specific part of the body being scanned and repeatedly sends out x-ray beams. As the beams pass through the body, the tissues absorb small amounts of radiation. Once the beam passes through, they are converted by light sensitive crystal det..

Formation of Image by a Plane Mirror - Ray Diagrams - The following rays are usually considered while constructing ray diagrams: A ray of light incident on a plane mirror at 90 degree gets reflected from the mirror along the same path. A ray of light falling on a plane mirror at any angle..

transmitted by T 1 and T 2 remain unaffected. However, when axes of the two crystals are at 90 0 to each other, light is completely cut off. This establishes that light waves are transverse in character. When unpolarised light is seen through a single crystal (polaroid), intensity of transmitted li..

Wave Nature of Particles - The suggestion that matter may have wave like properties was first put forwarded in 1924-1925 by Louis De Broglie. He argued that if light, which consists of waves according to classical picture, can sometimes behave like particles, then it should be possible fo..
