Waves – GCSE AQA Foundation Combined Science Physics revision notes

Waves covers Waves in air, fluids and solids and Electromagnetic waves in GCSE AQA Foundation Combined Science Physics. 7 lessons in 2 subtopics.

In a transverse wave, particles vibrate perpendicular (at right angles) to the direction of energy transfer, as in water ripples. The Transverse vs. Longitudinal Waves notes cover this in full.

Examples of transverse waves include ripples on a water surface, light waves and a wave on a rope flicked up and down. The Transverse vs. Longitudinal Waves notes cover this in full.

The wave equation is v = fλ: wave speed (m/s) = frequency (Hz) × wavelength (m). The Wave Equation & Changing Mediums notes cover this in full.

Visible light ranges from red, with a wavelength of about 700 nanometres, to violet, with a wavelength of about 400 nanometres. The The Electromagnetic Spectrum notes cover this in full.

The amplitude of a wave is the maximum displacement of a point on the wave away from its undisturbed position. The Wave Characteristics: Amplitude, Wavelength & Frequency notes cover this in full.

Wavelength is the distance from a point on one wave to the equivalent point on the adjacent wave. The Wave Characteristics: Amplitude, Wavelength & Frequency notes cover this in full.

Electromagnetic waves are transverse waves that transfer energy without transferring matter, consisting of oscillating electric and magnetic fields. The Introduction to Electromagnetic Waves notes cover this in full.

Wavelength is calculated with λ = v/f. The Wave Equation & Changing Mediums notes cover this in full.
