Circuits
the electrical potential difference between two points in a circuit.
What is voltage?
Invisible to the human eye, this helps the body produce vitamin D.
What is Ultraviolet radiation?
This phenomenon occurs when light bounces off a surface, like a mirror.
What is reflection?
The part of the wave that measures the loudness/volume
What is amplitude?
The transfer of heat through collisions between particles.
What is conduction?
The electrical charge that builds up in clouds and objects such as plastic rulers and balloons.
What is static electricity?
A family of waves ranging from radio waves through to gamma rays.
What is the electromagnetic spectrum?
This is the bending of light as it passes from one medium to another, changing its speed and direction.
What is refraction?
The part of the wave that measure pitch.
What is frequency?
The transfer of heat through the flow of particles.
What is convection?
Components are connected end-to-end so that the current flows through each component sequentially.
What is a series circuit?
These waves, located between radio waves and infrared radiation on the spectrum, are commonly used in cooking and in mobile phone signals.
What are microwaves?
A object that absorbs or reflects all the light striking it.
What is an opaque object?
The number of vibrations per second is measured by this.
Materials that are poor conductors, such as foam, wool and fibreglass.
This type of circuit has multiple paths for the current to flow through, each component being connected directly to the voltage source.
What is a parallel circuit?
A small range of the electromagnetic spectrum, lying between infra-red radiation and ultraviolet radiation.
What is the visible light spectrum?
This type of lens causes light rays to converge or focus, often used in magnifying glasses and cameras.
What is a convex lens?
Measured from crest to crest or trough to trough and is equal to one vibration.
What is wavelength?
Heat that can be transferred without any particles.
What is radiant heat?
The current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance.
What is Ohms Law?
Transverse waves that are unable to travel through some substance, but can travel through a vacuum.
What are electromagnetic waves?
The sideways reversal of images that you see when you look at yourself in the mirror.
What is lateral inversion?
The particles in this wave move backwards and forwards, the same direction as the energy transfer.
What are compression or longitudinal waves?
Like electromagnetic radiation, this head can be reflected, transmitted or absorbed.
What is radiation?
