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
plz dont give any dump answers!!!

Answer:
Define the radius of curvature of the spherical mirrors. Find the nature (type) of the 2x2 = 4 mirror and focal length of the spherical mirror whose radius of curvature is + 36 cm.

Answer:
The position of the image is in between F and C. The image formed is real and inverted. If the plane mirror is placed instead of the concave mirror, then the size of the image is the same as that of the object. If the convex mirror is placed instead of concave, then the image formed is virtual and erect.
Explanation:
1. The mirror is placed beyond the center of curvature, and an image is also formed. In the concave mirror, beyond the Centre of curvature and focus, a real image is formed. So, the position of the image must be in between focus and center of curvature.
2. In the concave mirror, between the Centre of curvature and focus, a real and inverted image is formed.
3. If the plane mirror is placed instead of the concave mirror, then the size of the image is the same as that of the object because a plane mirror always forms an image of the same size as of object.
4. In the convex mirror, if the object is in between pole and infinity, the image formed is virtual and erect. Here, the object is beyond C, so the image formed is virtual and erect.
Hence, it can be concluded that if a candle is placed beyond the center of curvature, the position of the image is between F and C. The image formed is real and inverted. If the plane mirror is placed instead of the concave mirror, then the size of the image is the same as that of the object. If the convex mirror is placed instead of concave, then the image formed is virtual and erect.
