We do not observe an upside-down image of the Sun through a pinhole camera because the Sun is symmetrical (spherical).
Why can't we see an upside down image of the sun through the pinhole camera?
Why cannot we see an upside-down image of a ball through the pinhole camera?
Give reasons.
(a) The sun, the earth and the moon must be in a straight line for an eclipse to occur.
(b) The penumbra is faint.
(c) An aeroplane or a bird does not cast a shadow upon the earth.
(d) We get an upside down image in a pinhole camera.
