A charge B current C electromotive force D potential difference Your answer [1] 3 © OCR 2022 Turn over 3 The diagram below shows the refraction of light at the boundary between two transparent materials X and Y. 1.5 n Y X 50° 20° The refractive index of material X is 1.5 and the refractive index of material Y is n. Which of the following expressions is correct? A n × sin 70° = 1.5 × sin 50° B n × sin 20° = 1.5 × sin 40° C 1.5 × sin 70° = n × sin 50° D 1.5 × sin 20° = n × sin 40° Your answer [1] 4 A student is carrying out the Young double-slit experiment using visible light. The distance between the slits and the screen is kept constant. The wavelength of light is λ and the separation of the slits is a. The following results are collected by the student. λ / nm a / mm A 450 0.20 B 510 0.15 C 550 0.25 D 610 0.30 Which combination of m and a will give the largest separation between the adjacent bright fringes? Your answer [1] 4 © OCR 2022 5 A car of mass 1000 kg is travelling on a straight and horizontal road. The driver applies the brakes. The speed of the car decreases from 20 m s–1 to 15 m s–1 in 2.4 s. What is the average power dissipated by the brakes? A 1.0 × 103 W B 5.2 × 103 W C 3.6 × 104 W D 8.3 × 104 W Your answer [1] 6 Two coherent waves are emitted from the sources X and Y. X Y P a b The diagram is not to scale. The waves at X and Y are in phase. The waves have wavelength 4.0 cm. The phase difference of the two waves meeting at point P is 270°. Which row gives possible distances for a and b? a / cm b / cm A 20.0 26.0 B 20.0 22.0 C 15.0 18.0 D 10.0 14. [Show More]
