Edexcel GCSE Combined Science CP4 and CP5 Waves overview quiz quiz

Matter from one place to another, but no energy

Both matter and energy together as it travels along

Energy without transferring matter

Neither matter nor energy, only a change in pressure

Parallel to the direction of travel, along the same line as the energy

In small circles, as each particle loops around its rest position

Stationary, since particles in a transverse wave do not move at all

At right angles (perpendicular) to the direction of travel

Sound

Light

A wave on a rope

An X-ray

Wave speed = frequency divided by wavelength

Wave speed = frequency times wavelength

Wave speed = wavelength divided by frequency

Wave speed = amplitude times frequency

16 m/s

8.5 m/s

4 m/s

0.0625 m/s

The distance covered by one complete wave cycle, called the wavelength

The number of complete waves that pass a point every second

The speed at which the wave travels through the medium

The maximum displacement from the rest position

Radio, microwave, infrared, visible, ultraviolet, X-ray, gamma

Gamma, X-ray, ultraviolet, visible, infrared, microwave, radio

Visible, radio, infrared, microwave, ultraviolet, gamma, X-ray

Microwave, radio, infrared, visible, X-ray, ultraviolet, gamma

Different speeds depending on frequency

The same speed (the speed of light)

The speed of sound

Zero speed

Radio waves

Infrared

X-rays

Microwaves

It causes echoes when it reflects off hard surfaces such as walls

It cannot be detected by any instrument, so it is impossible to measure

It is too weak to have any effect on the human body at all

It can damage skin cells and increase the risk of skin cancer

Increases

Decreases

Stays the same

Becomes zero

It bounces straight back the way it came, as if hitting a mirror

It changes direction because its speed changes

It disappears completely and no light passes into the glass

It speeds up inside the glass and bends away from the normal line
