beautiful patterns are formed in a kaleidoscope because of multiple reflection . explain and specify how it is different from a
periscope by diagrams.
1 answer:
Periscope is a tube containing mirrors or prisms for seeing things which are otherwise not possible to see due to some obstacle. Two mirrors are aligned at 45 degrees through which light bounces off and enables the observer to see beyond the obstacle. This is specially used in submarines.
A kaleidoscope is an optical device which contains mirrors and colored glass pieces in a tube. When the tube is rotated, beautiful patterns are formed due to multiple reflections.

<u>Answer:</u>
The power and voltage are related through Power Rule .
<u> Explanation : </u>
Power Rule states that the current I that flows the element in the circuit with a loss in voltage V, then the amount of power dissipated by that element in the circuit is the multiplicative product of voltage and the current.
Mathematically, power law is
The rate of work done or the rate of energy consumption or production is termed as power.Unit of power is denoted as W(watts).
Potential energy between any two points on a circuit is called as Voltage and is measured in volts (V) .
