05

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.

06

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.

07

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.

Open guide
08

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.

Open guide
09

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.

Open guide
10

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.

Open guide
11

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.

12

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.
