- Q1
1. Which is the correct orientation of the image produced by a Galilean telescope with respect to the object?
Upright
Virtual
Real
Inverted
30s - Q2
2. Why do astronomers prefer to use reflecting telescope in viewing astronomical objects?
It collects less light than lenses.
It can preserve the colors of the object.
It produces an upright image of the object.
It creates a clearer image of the object.

30s - Q7
7. Which shows the correct sequence of image formation in reflecting telescopes?
I. The light rays refract on the eyepiece producing an enlarged image. II. Light from the distant object enters the telescope.
III. Light converges after hitting the parabolic mirror.
IV. A plane mirror catches and redirects the light.

8. What happens to the image formed in a compound microscope when the eyepiece lens is adjusted far from the focal point of the objective lens?
No image will be formed.
The image will be magnified.
The image will diminish.
Image will become blurred.

Single convex lens
Two convex lenses
Concave mirror and plane mirror
30s - Q10
10. Reflecting telescopes and microscopes produce an enlarged image of the object. Which is TRUE about these optical instruments?
Microscopes are for tiny objects; telescopes are for distant objects.
Both optical instruments produce real images.
Both optical instruments produce an inverted image.
Microscopes are for distant objects; telescopes are for tiny objects.
