Fibre optics:
Light travels in straight lines, even though lenses and mirrors can deflect it, light still travels in a straight line between optical devices. This is fine for most purposes; cameras, binoculars, etc. wouldn't form images correctly if light didn't travel in a straight line. However, there are times when we need to look round corners, or probe inside places that are not in a straight line from our eyes. That is why "FIBRE OPTICS" have been developed.
The working of optical fibres depend on the basic principle of optics and the interaction of light with matter. From a physical standpoint, light can be seen either as "Electromagnetic Waves" or as "Photons". For optics, light should be considered as rays travelling in straight lines between optical elements, which can reflect or refract (bend) them.
Light is only a small part of the entire spectrum of electromagnetic radiation. The fundamental nature of all electromagnetic radiation is the same: it can be viewed as photons or waves travelling at the speed of light (300,000 km/s) or 180,000 miles/sec).
In the thin lens equation first prove that Zz = f*f (Hint use this diagram along with the characteristics of similar triangles). Then use this equation along with the act that Z^
A circuit which employs a DIRECT CURRENT source has a branch which contains a capacitor. After the circuit has reached a steady state, what is the magnitude of the current in the c
Determine the inductance of a solenoid of 2000 turns round uniformly over a length of 50 cm on a cylindrical paper tube 4 cm in diameter. The medium is air.
Calculate the moment of inertia of An 8.00-kg cylinder, of length 19.5cm and diameter 12.0 cm,about the central axis of the cylinder,if the cylinder is (1) thin-walled and hollow,
A bomber plane moves horizontally with a speed of 500 m/s and a bomb released from it, strikes the ground in 10 sec. angle at which it strikes the ground will be (g=10m/s) 1. tan
Explain the Vector Addition of Velocity Of course the velocity is relative to how you indicate the position d. If you are moving in water that is itself moving, then your full
Archimedes' principle A body which is submerged into a fluid is buoyed up through a force equal in magnitude to the weight of the fluid which is displaced, and directed upward
A positively-charged subdivision is moving southward in a downward-directed uniform magnetic field. The magnetic force is the merely force if any acting on the particle. Throughout
Friction is a microscopic constant and so macroscopic level area does not matter. But area would matter if the object we''re putting under study was microscopic, which isn''t in o
