Question

Feb is doing an experiment as shown above. He draws a straight line on the table. At one end of the line, he placed a concave mirror of focal length 30 cm. Marked principal focus (F) and center of curvature (C) on the line. He fixed a burning candle on the principle focus in such a way that it is at a slight distance from the center of curvature. Arranged a screen in such a way that a clear image is obtained on the screen.
1 What is the position of the image?
2 The image formed is
3 If the plane mirror is placed instead of the concave mirror, then the size of the image is
4 If the convex mirror is placed instead of concave, then the image formed is

Answer 1
