K.C.S.E Physics Q & A - MODEL 1998PP2QN07
a) Fig. 6 shows an object, 0.3cm high placed in front of a concave mirror. C is the centre of curvature of the mirror. The diagram is drawn to scale:(1cm: 2cm)
Draw a ray diagram, on figure 6, and determine the size of the image produced.
b) Table 3 shows the object distance y and the corresponding image distance v, for an object placed in front of a concave mirror.
i) Complete the table and plot a graph of 1/v (y-axis) against 1/u (give your answers to 3 decimal places).
ii) From the graph, determine the focal length of the mirror.
