AQA GCSE Physics 4.6 Waves overview quiz quiz

Parallel to it, along the same line as the energy moves

In a circle around it, looping back to where they started

In exactly the same direction as the energy is transferred

Perpendicular (at right angles) to it

Energy

Matter

Mass

Particles

The distance measured between two adjacent wave crests

The maximum displacement from the rest position

The number of complete waves passing a point each second

The time taken for one complete wave to pass a point

$0.0125\,m/s$

$40.5\,m/s$

$20\,m/s$

$80\,m/s$

Radio waves

The angle of incidence is twice the angle of reflection

The angle of incidence equals the angle of reflection

Light always passes straight through a surface

Reflection only happens at rough surfaces

The frequency of the wave changes

The wave is absorbed

The wave changes speed

The amplitude increases

It travels far too fast to pass through empty space

It is a transverse wave and so needs a solid surface

It has too high a frequency to move through a vacuum

It needs particles of a medium to vibrate

$20\,Hz$ to $20000\,Hz$

$2\,Hz$ to $200\,Hz$

$200\,Hz$ to $2000\,Hz$

$2000\,Hz$ to $200000\,Hz$

It emits its own red light from inside the object

It reflects red light and absorbs the other colours

It transmits red light straight through and reflects none

It absorbs the red light and reflects all the other colours
