Answers
Answer:
yes definitely.it produces complete image because the beam of light passes through the other half is enough..... however it's intensity become half
Explanation:
Indeed it will. Regardless of whether half of the arched focal point is secured with dark paper, the focal point will create a total picture. anyway the force of the picture might be less. It tends to be watched tentatively by utilizing a lit light and a raised focal point.
Trial -
1. Take a lit light and spot it before an arched focal point mounted on a plane surface.
2. Move the flame along the pivot of the plane to acquire the full picture on the screen. When the full picture is watched, mark the situation of the flame without moving it.
3. Presently spread the lower definite portion of the focal point with a dark misty paper. Try not to change the situation of the light.
4. Now, you will watch a full picture of the flame, however you will find that the force is diminished. This is on the grounds that the secured piece of the focal point does not enable light to go through it. So the measure of light arriving at the screen is decreased.
