(ii) Explain why one of the other rays would not have been suitable. (b) As a result of his injuries, Martin will have to spend a lot of time on his back unable to raise his head. His classmates have designed a pair of special spectacles using triangular glass prisms instead of lenses. One of these prisms is shown below.

(ii) What name is given to the effect which the prism has on light? TOTAL 20
5 Standard Grade Physics Health Physics Ink Exercise C1 1. Ultrasound is used to obtain information about the growth of unborn babies. Ultrasound of frequency 6.0 MHz is transmitted through the mother s body at a speed of 1500 m/s. (a) What is the wavelength of the ultrasound in the mother s body? (b) Why is ultrasound, rather than X-rays, used to obtain information about the unborn baby? 2. During a game, a player injures a knee. An X-ray is taken to check whether the leg has been broken, Ultrasound is used to determine if any fluid has formed in the knee. Figure 1 shows the position of the X-ray transmitter and figure 2 the position of the ultrasound transmitter and receiver in front of the knee. (a) (i) Copy figure 1 and indicate where the receiver for the X-rays should be placed. (ii) State why the ultrasound transmitter and receiver are on the same side of the knee as shown in figure 2. (iii) It is decided to treat the knee injury using ultrasound to speed the healing process. The ultrasound used in the treatment has a power of 8W. The energy to be delivered to the site of the injury is 2400J at each treatment. How many minutes should each treatment last? (b) Read the following passage. The limit of human hearing is 20kHz but other animals, such as bats and dolphins, make use of sound in the khz range. Sound above the range of human hearing is called ultrasound. Ultrasound behaves in a similar manner to audible sound, having a speed of 340 m/s in air, a speed of 1500 m/s in soft tissue and a speed of 4100 m/s in bone. Ultrasound is used not only to diagnose the cause of injury but also to help in the healing of injuries. When used in the healing process absorption of ultrasound takes place. (i) State the lowest frequency of ultrasound. (ii) What is the speed of ultrasound in soft tissue? (iii) State whether energy is absorbed or reflected when ultrasound is used to help the healing process.
6 3. Karen is tidying the reading spectacles on display in a store. The spectacles on the display are labelled 4.0 D, 3.25 D, 2.75 D and 2.5 D. She notices that the label is missing from one pair. Karen is asked to label correctly this pair of spectacles. She uses one of the spectacle lenses to focus a sharp image of a far-away window on to a piece of paper as shown below. The distance between the lens and the paper is 40 cm. Which label should Karen attach to the spectacles? You must show clearly your working which leads you to your answer. 4.
