The virtual reality headset in Fig. 6.1 includes a display and a lens, as shown in Fig. 6.2. For the lens, the display acts as the object. The lens works like a magnifying glass and produces a virtual image of the display.
(a(i))[1]
Describe the position of the display in relation to the focal length of the lens so that the lens functions as a magnifying glass for the image on the display.
(a(ii))[1]
Explain how a virtual image is formed.
(b(i))[3]
On Fig. 6.3, draw a ray diagram to show the formation of the virtual image I.
(b(ii))[1]
Determine the focal length of the lens.
