Plant-pollinator Interactions

Abstract Very little work has been done on the evolution of floral colour diversity, outside of Europe and the Middle East. In particular, we know almost nothing about the evolution of the Australian flora in the context of hymenopteran visual systems. Such a study is likely to be important due to the geologically long isolation […]

Light Emitting Diode

Introduction Alight-emitting diode(LED) is asemiconductorlight source. LEDs are used as indicator lamps in many devices and are increasingly used for otherlighting. Introduced as a practical electronic component in 1962,early LEDs emitted low-intensity red light, but modern versions are available across thevisible,ultravioletandinfraredwavelengths, with very high brightness. When a light-emittingdiodeis forwardbiased(switched on),electronsare able torecombinewithelectron holeswithin the device, […]

Sciences Dissertations | Photoelectric Effect Electrons

Assessment Task Topic: The Photoelectric Effect 1. Introduction The photoelectric effect is the name given to the phenomenon whereby electrons are emitted from a metal when exposed to electromagnetic radiation of the appropriate frequency. It was first discovered by Heinrich Hertz in 1887, but remained a conundrum to many scientists who sought to explain it, […]

The Variation of Light Intensity with Distance

The variation of light intensity with distance; namely the inverse square law of light intensity with distance. Background Theory Light emitted from any kind of source, e.g. the sun, a light bulb, is a form of energy. Everyday problems such as lighting required for various forms of labouring or street illumination, require one to able […]

Refraction Refraction refers to the bending of the transmitted light at the interface between two transparent materials. The angle of refraction depends on the angle of incidence and the relative speeds of the light in the two different media and can be found from the relationship [pic] From this equation we see that the direction […]

An Inconvenient Truth

When oceans get warmer, harsher storms form. The moisture content and wind capacity increases of a hurricane as it goes over warmer waters (could be convection). As the storm goes over those water, the energy from the water particles in the ocean transfer the energy into the water particles in the air, transferring its heat […]

Einstein’s Theory of General Relativity

In Albert Einstein’s theory of special relativity, he investigated and discovered how light’s speed was not dependent on its observer’ movement or motion. Einstein concluded that because space and time work as a solo continuum (based on the idea that inside a vacuum, regardless of an observer’s speed, light’s speed remains constant), physics’ fundamental properties […]

Albert Einstein – German-Born American Physicist and Philosopher

Albert Einstein is a German-Born American Physicist and philosopher who is generally acknowledged as the preeminent scientist of the twentieth century who challenged and disproved fundamental ideas concerning the physical universe. His theories changed the way physicists think about the universe, treating energy and matter as interchangeable and linking space with time and gravitation. His […]

Can Trees be Precursors for Earthquake Prediction?

This project investigates trees, earthquakes, atmosphere and ionosphere as a coupled system to see if trees can be used as precursor for short term earthquake prediction alongside other long, intermediate and short term precursors. History has shown animals can and have predicted earthquakes (Cao et al., 2018, Tong 1988), but the general tone of this […]
