Open guideWaves
Transverse and longitudinal waves, v = fλ, the electromagnetic spectrum, reflection, refraction and sound.
Space physics
The solar system, gravity and orbits, the life cycle of stars, red shift and the Big Bang — GCSE Physics rather than Combined Science on most specifications.
Transverse and longitudinal waves
Teacher-written GCSE Physics revision on transverse and longitudinal waves: oscillations versus energy transfer, amplitude, wavelength, frequency, period, and why sound needs a medium but light does not.
The electromagnetic spectrum
Teacher-written GCSE Physics revision on the electromagnetic spectrum: radio to gamma in order of frequency, 3 × 10⁸ m/s in vacuum, and one use and one hazard for each region you are asked about.
Wave speed
Teacher-written GCSE Physics revision on wave speed: v = fλ with a full substitution, v = d/t, converting MHz and centimetres, and why speed is a property of the medium in ripple-tank practicals.
Refraction
Teacher-written GCSE Physics revision on refraction: waves changing speed and direction in a new medium, towards or away from the normal, light in glass, and why wavelength changes but frequency does not.
Infrared radiation
Teacher-written GCSE Physics revision on infrared radiation: emission and absorption by surfaces, the required practical, black-body behaviour at GCSE, and how IR sits in the electromagnetic spectrum.
The solar system
GCSE Physics only (not Combined Science): teacher-written revision on the solar system, gravity and orbits, planets, moons, satellites, and why mass is unchanged while weight depends on g.
Life cycle of stars
GCSE Physics only (not Combined Science): teacher-written revision on star formation, main sequence equilibrium, Sun-like versus massive-star pathways, supernovae and how elements heavier than iron are made.
Red shift
GCSE Physics only (not Combined Science): teacher-written revision on cosmological red shift, Hubble’s pattern that distant galaxies recede faster, and how that supports an expanding Universe.
The Big Bang
GCSE Physics only (not Combined Science): teacher-written revision on the Big Bang model, red-shift evidence, cosmic microwave background radiation, and why alternative steady models struggled.
Waves required practical
Plan the GCSE Physics waves investigation: reflection and refraction with a ray box or ripple tank, angle i equals angle r, Snell’s law at GCSE level, measuring angles from the normal and fair testing.
