Question

Which is true of a compound microscope?

Question 1 options:

	Uses two converging lenses
	The optics are reversed from those of a refracting telescope
	The object to be viewed to be enlarged is placed just outside the focal point of the lens
	All of the above An optical surface is converging if . . . Question 2 options: Parallel incident rays are bent so they intersect after interacting with the surface Parallel incident rays are bent so they intersect before interacting with the surface If the surface perfectly absorbs parallel rays If the surface perfectly reflects parallel rays The standard near point distance in a compound microscope is . . . Question 4 options: Around 25 cm The closest point to the eye at which an object can be brought into focus Varies from person to person and may change throughout a person’s life All of the above For a refracting telescope to be of any value in seeing objects far away . . . Question 5 options: The focal length of the objective lens should be less than the focal length of the eye piece The focal length of the objective lens should be equal to the focal length of the eyepiece The focal length of the objective lens should be greater than the focal length of the eyepiece It has nothing to do with focal length A real image . . . Question 6 options: Can be focused on a screen Is produced by a mirror on the same side as the object Is produced by a lens on the opposite side as the image All of the above
