This tour shows a range of equipment and facilities available in one of our modern, dedicated laboratories.

The interactive version allows you to walk through the lab and get a 360° view of the facilities.

Introduction

Our professional technicians have set out 14 experiments to showcase the extensive range of equipment available in the main undergraduate Physics lab.

Rotational motion

This experiment investigates core physics concepts such as rotational kinetic energy, angular momentum and moments of inertia using computer-based data logging.

 Experiment 1: Rotational motion

Plasma generation

This experiment utilises kV potentials to break down a variety of gases, creating plasma: the fourth state of matter. It's designed to measure the effect of pressure of the breakdown potential of the gas, as well as undertaking finite element modelling of the electrodes.

Experiment 2: plasma generation

Ultrasound measurement using pulse-echo techniques

This experiment underpins the basic science of sound propagation by exploring the use of ultrasound for spatially mapping structure in solids. This technique has applications ranging from medical imaging to determination of structural integrity in engineering.

Experiment 3: Ultrasound measurement using pulse-echo techniques

Microwave physics

This equipment explores the transmission of microwave frequency signals along and between strip lines and antennae. It demonstrates the properties of electromagnetism used in real world applications such as mobile phone antenna design and operation.

Experiment 4: microwave physics

Speed of light

This is a demonstration of the measurement of one of nature's most fundamental constants, the speed of light, with the use of lasers and advanced use of oscilloscopes.

Experiment 5: Speed of light

 

Magnetic field uniformity in a solenoid

This demonstration measures and spatially maps the magnetic field strength of a solenoid utilising a Hall effect sensor.

Experiment 6: Magnetic field uniformity in a solenoid

 

Biot savart

This experiment uses a computer interfaced Hall probe to measure magnetic field intensity generated by a long straight current carrying wire.

Experiment 7: Biot savart

 

The band gap of semiconductors

This practical experiment explores the physics of semiconductors; the underpinning science of the 20th-century technological revolution. It uses a computer controlled monochromator to perform infrared spectroscopy on numerous materials in order to measure the 'band gap', a characteristic electronic property of semiconducting materials.

Experiment 8: The band gap of semiconductors

 

Torque on magnetic dipoles

This equipment is used to investigate magnetic dipoles and their interaction with a uniform magnetic field. This macroscopic demonstration of electromagnetism offers insight into the microscopic mechanisms which occur regularly within atoms, affecting their electronic structure and spectroscopic signatures.

Experiment 9: Torque on magnetic dipoles

 

Hall effect in p-type Ge

This demonstration investigates the Hall effect. Materials carrying current while in a region of magnetic field will generate a 'Hall voltage' related to both the electrical carrier density and magnetic field strength. This effect can be used to investigate material properties, or measure magnetic fields.

Experiment 10: Hall effect in p-type Ge

 

Temperature variation of electrical resistance

This practical experiment uses liquid nitrogen cooling to investigate the effects of cryogenic temperatures on electrical resistance, which can be used to investigate superconductivity and demonstrate magnetic levitation.

Experiment 11: Temperature variation of electrical resistance

Charge decay from a capacitor

This lab bench is set up with a modern storage oscilloscope to monitor the voltage across a discharging capacitor.

Experiment 12 - Charge decay from a capacitor

 

Properties of liquid nitrogen

This set up uses cryogenic materials to determine the latent heat of vaporisation of liquid nitrogen.

Experiment 13: Properties of liquid nitrogen

 

Photoelectric effect

This practical experiment investigates the physics which gained Einstein his Nobel prize, and kickstarted the quantum revolution: the photoelectric effect. It considers the work function of a UV irradiated photocathode and applies Einstein's theoretical insights to measure Planck's constant.
