describes a wave where the direction of oscillation is 90° to the direction of energy transfer

the greatest distance a material moves from the rest position when a wave passes through that material

the process of waves ‘adding up’ or ‘cancelling out’ as they pass through each other

lines drawn to represent the positions of the peaks of a wave

Sound waves

Speed of sound

Ultrasound

In the Measuring waves unit, pupils will build on this knowledge to learn about the measurable features of a wave, the relationship between them and the wave equation.

In the Making images unit, pupils learnt that white light is made of different colours that can be detected by the eye, and how pinhole cameras and lenses form clear images.

This unit explores the nature of sound and water waves, including transverse and longitudinal motion, wave reflection, superposition, and the speed of sound in various media. It covers sound production, detection, and auditory ranges, emphasising data interpretation, and basic calculations.

Waves

Which of the following words means back-and-forth movement?

The diagram shows a water wave. Match the letters with the correct labels.

In a {{}} wave such as a water wave, the repeating movements of parts of the medium are at 90° to the direction of energy transfer.

Water waves transfer energy and particles in one direction.

In a water wave, particles of water move repeatedly right and left.

Wavefronts are lines drawn to show the positions of crests of a wave.

Which of the following statements is correct?

Which of the following is a word that describes what waves do when they pass through each other?

The diagram shows the resultant wave when two waves pass through each other. Which of the following shows two waves that combine to form this resultant wave at this moment?

Which of the following are types of wave?

Which of the following shows parallel lines?

Which of the following correctly shows reflection of a light ray off a mirror?

line showing where two different types of material meet

arrow showing the direction of a wave after reflection

arrow showing the direction of the wave as it approaches a mirror

imaginary line at right angles to a mirror at the point a ray meets it

Each of these terms describes a line that can be seen in a ray diagram for the reflection of light. Match each term with its definition.
