Term 1G2 / G3

Sec 4 Combined Science (Physics) WA1 practice paper

WA1 is usually the first weighted assessment of the Sec 4 Combined Science (Physics) half, held towards the end of Term 1. It tests the waves toolkit — wave terms, v = fλ, sound and echoes — plus the electromagnetic spectrum and the reflection–refraction–lens story of light.

Revision checklist

Work v = fλ forwards and backwards, converting MHz and kHz before dividing.
Describe waves with all five terms (speed, frequency, wavelength, period, amplitude) and both graph types.
List the seven EM regions in order and match each to a use and a hazard.
Draw reflection and refraction ray diagrams with the normal marked; measure angles from it.
Quote the converging-lens image table (beyond 2F, at 2F, F–2F, inside F) from memory.
Sit the Chapter 1–3 quizzes first, then this paper in one 55-minute block.

Exam tips

Always draw the normal first in ray questions — angles are measured from it.
In v = fλ questions, convert prefixes (MHz, nm) before any division.
Echo questions carry a factor of 2: state the out-and-back trip explicitly.
Name lens images with all three descriptors: real/virtual, upright/inverted, magnified/diminished.

Questions about the WA1

What is tested in Sec 4 Combined Science (Physics) WA1?

Most schools test Chapters 1–3: wave terms and v = fλ, sound and echoes, the EM spectrum with uses and hazards, and light — reflection, refraction with sin i/sin r, refractive index and converging-lens images. Your school’s outline gives the exact scope.

Is total internal reflection tested?

Not in Combined Science — total internal reflection and critical angle are Pure Physics topics. This paper stays within the Combined syllabus.

Is this paper based on a real school paper?

No. QuizQuip papers are original material written against the syllabus. QuizQuip is not affiliated with MOE or SEAB.
