Question:
You are provided with the following apparatus.
- a Convex lens
- A candle
- White screen
- Lens holder
- Metre rule
- Set up the apparatus as shown in the figure below.
- Place a lighted candle at object distance, U = 20cm. Move the screen, towards or away the lens until a sharp image of the candle flame is obtained on the screen. Measure the distance V and record the results in the table below.
- Repeat the same for other values of U as shown in the table and fill their respective values of V. (5mks)
- Plot a graph of UV (cm2) against (U + V) (cm) Determine the slope of the graph
- 2 New dry cells
- An ammeter
- A mounted wire labelled AB
- A cell holder
- A switch
- Connecting wires
- Draw a circuit that can be used to determine the resistance of the wire AB.
Determine the power of the lens used in the experiment.
