In an experiment to determine the focal length (f) of a concave mirror by the u-v method, a student places the object pin A on the principal axis at a distance x from the pole P. The student looks at the pin and its inverted image from a distance keeping his/her eye in line with PA. When the student shifts his/her eye towards left, the image appears to the right of the object pin. Then,

A student performed the experiment of determining the focal length of a concave mirror by u-v method using an concave mirror used is 24 cm.The maximum error in the location of of the image can be 0.2 cm.The 5 sets of (u,v) values redcorded by the student in cm are :(42,56),(48,48),(60,40),(66,33),(78,39).The data set(s) that cannot come from experiment and is (are) incorrectly recorded is (are)

In an experiment on photoelectric effect, the following graphs were obtained between the photoelectric current 'I' and anode potential V. Name the characterstics of this incident radiation that was kept constant in this experiment.

What is the relation between focal length and radius of curvature of a concave mirror? What is focal length of a plane mirror?

The plates of a parallel plate capacitor have an area of 90 cm^2 each and are separated by 2.5 mm. The capacitor is charged by connecting it to a 400 V supply. (a) How much electrostatic energy is stored by the capacitor? (b) View this energy as stored in the electrostatic field between the plates, and obtain the energy per unit volume u. Hence arrive at a relation between u and the magnitude of electric field E between the plates.

A short linear object of length b lies along the axis of a concave mirror of focal length f at a distance u from the pole. What is the size of the image?
