See it on the paper →An astronomer looks at a distant star. Fig. 9.3 shows the astronomer’s eye and two parallel rays of light from the distant star. lens Fig. 9.3 Complete Fig. 9.3 to show the two rays focused onto the back of the astronomer’s eye by the
See it on the paper →State why a wave is refracted as it moves from one medium to another.
See it on the paper →There is ice on a lake near the house. Fig. 6.3 shows a ray of light from the Sun incident on the ice. air ice Fig. 6.3 State the term used to describe the change in direction of light as it enters the ice.
See it on the paper →There is ice on a lake near the house. Fig. 6.3 shows a ray of light from the Sun being refracted as it moves into the ice. air ice Fig. 6.3 Explain why the ray of light changes direction on entering the ice.
See it on the paper →State the property of light shown in Fig. 6.2.
See it on the paper →Draw on Fig. 3.1 the ray of light as it emerges from the glass block. Label the line X.
See it on the paper →• She varies the angle of incidence i of the light entering the glass block as shown in Fig. 3.2. ray box incident ray normal semi-circular glass block i r refracted ray Fig. 3.2 • • She measures and records the angle of refraction r for each angle of incidence i shown in Table 3.1. If no refracted ray emerges from the...
See it on the paper →A student predicts that doubling the angle of incidence i will always double the angle of refraction r. Suggest whether the results in Table 3.1 support this prediction. Justify your answer with reference to the results in Table 3.1.
See it on the paper →When no light emerges from the straight edge of the glass block, all the light has been reflected back inside the block. The smallest angle of incidence at which all the light is reflected back inside the glass is called the critical angle. Use your results in Table 3.1 to estimate a value for the critical angle. estim...
See it on the paper →Suggest how this experiment could be improved to find a more accurate value for the critical angle.
See it on the paper →The two parallel rays had to continue until reaching the eye, refract in the lens, and converge on the back of the eye. Candidates should be familiar with the formation of an image by a thin converging lens. A small number of candidates gained full credit in this question. Common mistakes were showing the rays focusing before the back of the eye and refraction of the light before reaching the eye,...

Some candidates gained credit by stating refraction. Candidates should ensure they use the correct spelling for refraction. ‘Reflaction’ was not accepted since it was not clear that reflection was not intended.
— Examiner report, February/March 2023, 0653/32 Q6(c) (Cambridge)
Many candidates knew that light rays refract when passing across the boundary between different media. The change in light speed was less well-known.
