List of Physics Practical for ISC Class 12
- To find focal length of a convex lens by using u-v method (no parallax method)
Using a convex lens, optical bench/metre scales and two pins, obtain the positions of the images for various positions of the object; f2f.
Draw the following set of graphs using data from the experiments –
(i) v against u. It will be𝑢𝑢𝑣𝑣a curve.
(ii) Magnification (m = ) against v which is a straight line and to find focal length by intercept.
(iii) y = (100/v) against x = (100/u) which is a straight line and find f by intercepts. - To find f of a convex lens by displacement method.
- To determine the focal length of a given convex lens with the help of an auxiliary convex lens.
- To determine the focal length of a concave lens, using an auxiliary convex lens, not in contact and plotting appropriate graph.
- To determine focal length of concave mirror by using two pins (by u-v method).
- To determine the refractive index of a liquid by using a convex lens and a plane mirror.
- To determine the focal length of a convex mirror using convex lens.
- Using a metre bridge, determine the resistance of about 100 cm of (constantan) wire. Measure its length and radius and hence, calculate the specific resistance of the material.
- Verify Ohm’s law for the given unknown resistance (a 60 cm constantan wire), plotting a graph of potential difference versus current. Also calculate the resistance per cm of the wire from the slope of the graph and the length of the wire.
- To compare emfs of two cells using a potentiometer.
- To determine the internal resistance of a cell by a potentiometer.
- From a potentiometer set up, measure the fall in potential (i.e. pd) for increasing lengths of a constantan wire, through which a steady current is flowing; plot a graph of pd (V) versus length (l). Calculate the potential gradient of the wire and specific resistance of its material. Q (i) Why is the current kept constant in this experiment? Q (ii) How can you increase the sensitivity of the potentiometer? Q (iii) How can you use the above results and measure the emf of a cell?
- To verify the laws of combination of resistances (series and parallel) using metre bridge.
