AQA AS Physics mock draft, 26–31 Oct. Draft coverage: Physics AS Paper 1. Reviewed for an original-practice sitting; check student availability before registering. Marking and results will follow later, after separate approval. Eligible new accounts receive a five-day Pro trial when signup email verification completes. Previous trials keep their original expiry. After expiry, new papers need Pro unless you have an explicitly confirmed free sitting offer for this event. That offer adds no Pro time or AI learning. Saved attempts and released results remain readable. No card or automatic charge.

The wave equation is c = fλ, where c is wave speed in m s⁻¹, f is frequency in Hz and λ is wavelength in m. The Understanding Progressive Waves notes cover this in full.
Snell's law states that n₁ sin θ₁ = n₂ sin θ₂, where n₁ and n₂ are the refractive indices of the two media and θ₁ and θ₂ are the angles the ray makes with the normal on each side of the boundary. The Refraction and Snell's Law notes cover this in full.
Examples of transverse waves include waves on a stretched string, all electromagnetic waves such as light, radio waves and X-rays, and, as an approximate model, water surface waves. The Longitudinal vs. Transverse Waves notes cover this in full.
Examples of longitudinal waves include sound waves in air, compression waves along a slinky spring and ultrasound waves used in medical imaging. The Longitudinal vs. Transverse Waves notes cover this in full.
In a transverse wave the particle or field oscillation is perpendicular to the direction of energy propagation, while in a longitudinal wave the particles oscillate parallel to it, producing compressions and rarefactions. The Longitudinal vs. Transverse Waves notes cover this in full.
A transverse wave is a wave in which the oscillation of particles, or of electric and magnetic fields, is perpendicular to the direction of energy propagation. The Longitudinal vs. Transverse Waves notes cover this in full.
Wavelength is the minimum distance between two points oscillating in phase, measured in metres. The Understanding Progressive Waves notes cover this in full.
A longitudinal wave is a wave in which particles oscillate parallel to the direction of energy propagation, producing compressions (regions of high pressure) and rarefactions (regions of low pressure). The Longitudinal vs. Transverse Waves notes cover this in full.
