Figure 1 What is distance ‘X’ called? [1 mark] 0 1 . 2 Lenses can be used to form the image of an object. Complete the ray diagram in Figure 2 to show how a convex lens forms the image of the object. Use an arrow to represent the image. [2 marks] Figure 2 3 *03* Turn over IB/G/Jun19/8463/2H Do not write outside the box 8 Figure 3 shows how a concave lens forms the image of an object. Figure 3 0 1 . 3 Give one similarity and one difference between the image formed by the convex lens and the image formed by the concave lens. [2 marks] Similarity Difference 0 1 . 4 A person uses a lens to read the letters on the back of a coin. The image height of the letters on the coin is 9.0 mm The magnification produced by the lens is 6.0 Calculate the height of the letters on the coin. Use the Physics Equations sheet. [3 marks] Height = mm 4 *04* IB/G/Jun19/8463/2H Do not write outside the 0 2 Figure 4 shows the apparatus used to investigate the waves in a stretched string. box Figure 4 The frequency of the signal generator is adjusted so that the wave shown in Figure 4 is seen. At this frequency the string vibrates between the two positions shown in Figure 4. 0 2 . 1 The wavelength of the wave shown in Figure 4 was measured as 80 cm What piece of apparatus would have been suitable for measuring this wavelength? [1 mark] 0 2 . 2 Write down the equation which links frequency, wavelength and wave speed. [1 mark] 0 2 . 3 The string in Figure 4 vibrates at 55 Hz Calculate the wave speed of the wave shown in Figure 4. Use data given in Figure 4. [3 marks] Wave speed =
