A student wants to project the image of a candle flame on a screen 80 cm in front of a mirror by keeping the candle flame at a distance of 20 cm from its pole.
- Which type of mirror should the student use?
- Find the magnification of the image produced.
- Find the distance between the object and its image.
- Draw a ray diagram to show the image formation in this case and mark the distance between the object and its image
Answer:
- Concave mirror should be used.
- Object distance, u = - 20 cm; image distance, v = - 80 cm;
magnification, m = ?
- Distance between the object and its image=v-u=60cm
