Required practicals

Investigate how the resonant frequency of a stretched string depends on its vibrating length, tension and mass per unit length.

Determine the wavelength of monochromatic light from two-source fringe spacing and from diffraction-grating angles.

Determine the local gravitational field strength from the motion of an object released from rest.

Determine the Young modulus of a wire from its dimensions and its elastic extension under known tensile forces.

Determine the resistivity of a metal wire from its diameter and the variation of resistance with measured length.

Determine a cell's emf and internal resistance from the variation of terminal potential difference with current.

Investigate how period depends on suspended mass for a spring and on length for a simple pendulum, then use linearised graphs to determine the spring constant and gravitational field strength.

Test Boyle's law at constant temperature and Charles's law at constant pressure using two clearly separated experimental branches.

Record capacitor charge and discharge curves and determine the time constant RC from a log-linear graph or a 1/e measurement.

Investigate how magnetic force depends on current, flux density and active wire length by measuring the corresponding change in a top-pan balance reading.

Use a search coil and oscilloscope to investigate how the induced-emf amplitude, as a proxy for changing flux linkage, depends on the angle between the coil normal and a magnetic field.

Test whether background-corrected gamma count rate varies as the inverse square of source-to-detector distance.
