Generally Waves
A physical phenomena that transfers energy (not matter) from one location to another.
What is a wave?
Longitudinal wave associated with verbal communication.
What are sound waves?
The range of light found between infrared and ultraviolet.
What is visible light/spectrum?
The result of the reduction of thermal energy.
What is cold?
What are electrons?
Cochlear implants enhance quality of life for people with hearing difficulties.
What is a social benefit of the development of sound technology?
Measured from trough to trough, or peak to peak.
What is wavelength?
Associated with the amplitude of a sound wave.
What is volume?
Is equal to the angle of incident.
What is the angle of reflection?
The transfer of heat energy that travels in waves.
What is radiation?
A closed pathway that allows charged particles to move from a power source to a range of electrical components.
What is a circuit?
PokemonGo and V-tubers are examples of this.
Technological developments utilising light.
Oscillations are parallel to the direction of energy transfer.
What are longitudinal waves?
Results in a sound lowering in pitch.
What is decreasing frequency?
Light refracts towards this quality of transparent medium.
What is more dense?
Is a poor conductor of thermal energy.
What is a good insulator?
Represents the flow of electrons.
What is current?
The greater energy efficiency of these reduced the amount of heat being generated by the highly resistant filament in incandescent bulbs, resulting in significantly lower energy consumption.
What are LED bulbs?
What is Hz (Hertz)?
Prevents the propagation of sound waves.
What is a vacuum?
The result of specific wavelengths of light being reflected off objects and interacting with the retina.
What is colour?
Explains why hot hair rises.
What is convection?
A circuit configuration that allows equal voltage across a system.
What are parallel circuits?
This phenomena helps explain the movement of tectonic plates.
What is convection?
This change in the tension of a rope increases the speed of the wave moving through it.
What is increasing the tension?
Phase inverted signals resulting in destructive waves.
How does noise cancelling technology work?
The scattering that occurs when particles smaller than the wavelength of light or electromagnetism interact with the radiation, causing phenomena such as the blue colour of the sky.
What is Rayleigh scattering?
Infrared radiation is absorbed and re-emitted by gases in the atmosphere, significantly contributing to man-made climate change.
What is the greenhouse effect?
Electric current is proportional to voltage and inversely proportional to resistance.
What is Ohm's Law?
This phenomena makes it possible to see distant object normally obscured by the curvature of the Earth, leading some conspiracy theorists to inaccurately conclude that the Earth is flat.
What is refraction?
