Read Relative speed of image
This SOF ISO pattern tests find man-image speed. Read the condition carefully, then use the method below before you solve.
Motion and force questions become simpler when direction, starting condition, time and the acting forces are marked first.
Trace the light ray before choosing an image
Trace the ray in the direction light travels
A ray travels from source to object and then to the eye. At a mirror, the angle of incidence equals the angle of reflection.
Find the tested idea
Turn the figure, table or rule into small labelled steps before looking at the options.
Work from the evidence
Choose two anchor features or one confirmed rule. Apply it consistently; an option with even one broken anchor is eliminated.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
