The Type of Mirror to Use for Projecting an Image of a Candle Flame on a Screen
To determine the type of mirror that should be used to project the image of a candle flame on a screen, we need to consider the properties of different types of mirrors: convex, plane, and concave.
Convex Mirror:
- A convex mirror is a curved mirror that bulges outward.
- It has a reflective surface on the outer side of the curved surface.
- Convex mirrors diverge light rays and form virtual, diminished, and upright images.
- The image formed by a convex mirror is always virtual and smaller than the object.
Plane Mirror:
- A plane mirror is a flat mirror with a smooth, reflective surface.
- It reflects light according to the law of reflection, where the angle of incidence is equal to the angle of reflection.
- Plane mirrors produce virtual, upright, and same-sized images.
- The image formed by a plane mirror is located behind the mirror at the same distance as the object.
Concave Mirror:
- A concave mirror is a curved mirror that bulges inward.
- It has a reflective surface on the inner side of the curved surface.
- Concave mirrors can either converge or diverge light rays, depending on the position of the object.
- When the object is placed beyond the focal point of a concave mirror, it forms a real, inverted, and diminished image.
- When the object is placed between the focal point and the pole of a concave mirror, it forms a virtual, upright, and enlarged image.
Explanation:
In this given scenario, the student wants to project the image of a candle flame on a screen. For this purpose, the image formed should be real and enlarged. Therefore, the student should use a concave mirror.
The focal point of a concave mirror is located on the same side as the object. As per the information provided, the flame is kept at a distance of 15 cm from the pole of the mirror. To form a real and enlarged image on the screen, the object should be placed between the focal point and the pole of the mirror.
By using a concave mirror, the light rays emitted by the candle flame will reflect off the mirror surface and converge to form an enlarged image on the screen. This type of mirror will allow the student to project the image of the candle flame on the screen, fulfilling the desired objective.
Therefore, the correct answer is option 'C' - concave mirror.

Explanation:
In this given scenario, the student wants to project the image of a candle flame on a screen. For this purpose, the image formed should be real and enlarged. Therefore, the student should use a concave mirror.
The focal point of a concave mirror is located on the same side as the object. As per the information provided, the flame is kept at a distance of 15 cm from the pole of the mirror. To form a real and enlarged image on the screen, the object should be placed between the focal point and the pole of the mirror.
By using a concave mirror, the light rays emitted by the candle flame will reflect off the mirror surface and converge to form an enlarged image on the screen. This type of mirror will allow the student to project the image of the candle flame on the screen, fulfilling the desired objective.
Therefore, the correct answer is option 'C' - concave mirror.
