Magnifying Power of a Simple Microscope
The magnifying power or angular magnification of a microscope may be defined as the ratio of the angle subtended at the eye by the image formed at the distance of the distinct vision to the angle subtended by the object when placed at the distance of the distinct vision. The ray..

When the Object is Between the Pole and the Focus
Here we consider a ray of light which is parallel to the principal axis and another ray which is passing through the centre of curvature. The ray which is passing through the centre of curvature retraces its path and the other ray which is parallel to the principal axis after reflection passes thr..

Any object which allows light to pass through it is known as a transparent object. The color of any transparent object is the color of the light transmitted by it. Ordinary window glass appears white because it allows all the colors in the white lig..

Experiments on Falling Objects and Conclusions
To understand how the resistance offered by air affects the rate of fall of freely falling objects, let us consider the following experiment. Drop a pebble and a piece of paper simultaneously from the same height. The pebble will hit the ground first. Now repeat the above experiment by c..

She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
I love the interaction and ability to explain the process of math problem in depth! Would like see the same for all future lessons one on one! THANK YOU!!!
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
