Answer 2

Answer:

Hello

there are many ways

The convex lens must have the focal length between 15 to 20 cm.

The convex lens must have a small aperture.

To avoid the flickering of the candle flame, the experiment can be conducted in calm air.

Perform the experiment in a dark room so as to obtain a distinct and sharp image of the candle flame.
