If you are searching for 1st Year Physics Chapter 10 MCQs with Answers Optical Instruments to prepare for Entrance Test, then here you are in the right place. This chapter is about different Optical Instruments that are based on the principle of reflection and refractions. First, there is the concept of magnifying power and resolving the power of these instruments. The simple Microscope working, its structure and its picture formation are discussed followed by the compound microscope. Then there is the Astronomical Telescope. There is a device called Spectroscope that is used to study spectra from different lights. Then there are fibre optics, it’s working, and their types. The last topic is Losses of power. Here below, you can find important MCQs of this chapter in quiz form.
