resolving power and magnifying power

Resolving Power - The ability of the instrument to resolve the images of two point objects lying close to each other. Due to the wave nature of light each point object produces its own diffraction pattern, which overlap, and the image can no longer be identified. ..

Magnifying power of an astronomical telescope may be defined as the ratio of the angle subtended at the eye by the image to the angle subtended at the eye by the object. From the ray diagram we know that: P l C is the focal length of the objective and P l D is the focal length o..

The magnifying power of a compound microscope is defined as the ratio of the size of the final image (I 2 ) as seen through the microscope to the size of the object as seen with a naked eye. Image Formation in a Compound Microscope = m o b j e c t i v e x m e y e p i e c e = m o..

A contractor wishes to lift a load of bricks from the sidewalk to the top of a building by means of a winch. Since we know the expression for work, we can calculate work to be done by the force applied by the winch to lift the load. We are interested in the rate at which it is done, that is, will t..

Power - Imagine two students positioned at track A and track B of 100 m length shifting 10 bricks from one end of the track to the other end. What is the amount of work done by each one of them? The amount of work done is same but the time taken to perform the work varies. In order to fin..

Simple Microscope or Magnifying Lens - Magnifying Lens It consists of a converging lens of small focal length. By keeping the object close to the lens, a virtual, erect and magnified image is obtained as sho..

Electric Power - Power is the rate of doing work or in other words, it is the work done in one second. If a current of 'I' amperes flows through a conductor of resistance 'R' ohm for a time 't' seconds when the potential difference across its ends is 'V' volt, then the electric ..
