Which kind of image can never be projected and forms where light rays appear to originate? virtual
real
inverted
enlarned

a) virtual

Explanation:

This is a lens problem, in this case the equation that describes the process is the constructor equation

        1 / f = 1 / p + 1 / q

where f is the focal length, weights the distance to the object and qq the distance to the image

In a projection system the image that we see is q, which can have several characteristics

a) virtual It can never be projected, since this image is formed by the extensions of the light rays, therefore it is not real but a construction of the brain that interprets where the rays must come from.

b) Real. This image can be projected since light rays pass through the image

c) Inverted. Inverted images are real so they can be projected, so rays pass through the image

d) expanded. In this case the image is greater than the object, this occurs when the object the distance to the image is greater than the distance to the object, therefore the distance q is negative, therefore this image is straight and is formed by the extensions from the rays and you can't project

increases it

d. air pressure decreases as altitude increases.
