SCOPE OF STUDY
5 main sub topics students should learn and understand in this
chapter are :
Effect of intensity and frequency of a light wave on the
photoelectrons produced
Photoelectric current against potential graph
Quantitative study of t
Physics
Sound & Light
Sound
Sound wave- longitudinal wave made by
vibrating material, carried through the medium,
transferring the Energy
Sound needs a medium, no sound in a
vacuum/space

Capacitors
Capacitors
A capacitor is a device for storing electric
charge.
It can be any device which can store charges.
Basically, capacitors consists of two metal
plates separated by an insulator. The insulator
is called dielectric. (e.g. polystyrene

Michael Faraday
Faraday was working with two coils
mounted on a wooden spool. Whenever
he put a large amount of current into
the primary coil, a small amount of
current was produced in the secondary
coil
