Q2PhysicsUnit 16: Optics
A reflecting telescope utilises:
Q3PhysicsUnit 16: Optics
Large astronomical telescopes always use as objective
Q4PhysicsUnit 16: Optics
To increase the magnification of a
telescope
Q5PhysicsUnit 16: Optics
A compound microscope has an objective lens of focal length and
an eye-piece of of focal length.
When the object is placed at from the objective, the final image is at the least distance of direct vision. Thus,
the magnification produced is
Q6PhysicsUnit 16: Optics
Assertion
If objective and eye lenses of a microscope are interchanged then it
can work as telescope.
Reason
The objective lens of telescope has small focal length.
Q7PhysicsUnit 16: Optics
A microscope is focused on a mark, then a glass slab of refractive index 1.5 and thickness of is placed on the mark to get the mark again in focus, the microscope should be moved
