- Q1
Which is the correct orientation of the image produced by a Galilean?
real
virtual
upright
inverted
30sS10FE-IIg-50 - Q2
Why do astronomers prefer to use reflecting telescope in viewing astronomical objects?
It creates a clearer image of the object.
It produces an upright image of the object.
It can collects less light than lenses
It can preserve the colors of the object.

30sS10FE-IIh-52 - Q6
A compound microscope uses a system of lenses. Which property of light is observed in this device?
Reflection
Dispersion
Diffraction
Refraction
30sS10FE-IIh-52 - Q7
Which shows the correct sequence of image formation in reflecting telescope?
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.
III, IV, I, II
II, III, IV, I
I, II, III, IV
IV, I, II, III
30s - Q8
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?
The image will be magnified
No image will be formed
Image will become blurred
The image will diminish
30sS10FE-IIh-52 - Q9
An enlarged image of a cell was flashed on a screen. Which optical set was able to produce the image?
concave mirror and plane mirror
concave mirror and convex lens
two convex lenses
single convex lens
30sS10FE-IIh-52 - Q10
Reflecting telescopes and microscopes produce an enlarged image of the object. Which is TRUE about these optical instruments?
both optical instruments produce real images.
Microscopes are for tiny objects; telescope are for distant objects.
Microscopes are for distant objects; telescopes are for tiny objects.
Both optical instruments produce an inverted image.
