What will happened to the image, if part of the ligh path were blocked. (Click the block button)


It only reduced the intensity of the image. You can drag any one of the dot in the simulation to change its setting.

the answer is the same for questions like this!

A student takes a convex lens and a piece of white card to a window. She moves the lens until an image of a distant building is seen on the card. Another student takes a second piece of card and gradually covers the lens, starting at the bottom.

Consider the following possible consequences:
The top of the image will disappear
The bottom of the image will disappear
The image will become less bright
Nothing will happen until just before the entire lens is covered

what do you think is the most likely answer?
