A student places a candle flame at a distance of about 60 cm from a convex lens of focal length 10 cm and focuses the image of the flame on a screen. After that he gradually moves the flame towards the lens and each time focuses the image on the screen.
In which direction-toward or away from the lens, does he move the screen to focus the image?
How does the size of the image change?
How does the intensity of the image change as the flame moves towards the lens?
Approximately for what distance between the flame and the lens, the image formed on the screen is inverted and of the same size?
Draw a diagram to represent a convex mirror. On this diagram mark principal axis, principal focus F and the centre of curvature C if the focal length of convex mirror is 3cm.
Identify the device used as a spherical mirror or lens in following cases, when the image formed is virtual and erect in each case.
Object is placed between device and its focus, image formed is enlarged and behind it.
